Human beings are born, formed and changed from one generation to the other through genetics. When a child enters the world, there is always a lot of excitement and uncertainty as which parent will the baby look like? Genes of the both parents determines the physical makeup of a child and therefore, genetics plays a very big role in human development. Genetics chromosomes are distributed equally by the parents to the child and they play a big role in the development of the child. Genes determines the development of a fetus inside its mother’s womb and outside of the mother’s womb.
Genes from parents are passed down to their children and this sets up their lifelong development. When a male cell meets with female reproductive cell, they start a process for a new life in a woman’s womb. The sperm has a different copy of the gene and an egg the same and so when they meet, two copies of genes are present and through them a new life begins and it will comprise both genes. From the eyes to the color of the hair, genetics plays a role in a person’s biological make up and development. Genes can predetermine many different characteristics in human development.
Genetics determines simple things as the ultimate height of a person. “The entire genetic code of a human is determined by the unique combination of a mother’s single ovum (egg) and a father’s single sperm” (Mossler, 2011). Therefore every person on the earth is a combination of their biological parents who in turn are a combination of their biological parents and the chain goes on and on. Genes are an important foundation of how one becomes and how they will develop from childhood to adulthood.
Studies have also shown that genetics also plays a part in illnesses and diseases that c...

...ir genetic material are passed on as DNA which is the map of the new unique human being formed after conception. The genetic material determines specific traits in the newly created life both physically, mentally and emotionally as the individual has to take after the mother and father. It can also determine if a genetic disease is to be in the future for this life. In essence, the role that genetics play in human development is the instructions under which we are all assembled.

Tay-Sachs disease is a rare and fatal genetic disorder that destroys neurons in the brain and spinal cord. The disease appears in three forms, Juvenile Onset, Late Onset (known as LOTS), and the most common form, Infantile (also known as Classic). The differences between the three forms of the disease are related to the age at which the symptoms of the disease begin to form. Tay-Sachs results from a deficiency of the enzyme hexosaminidase A, which plays a vital role in removing a fatty substance, called GM2 gangliosides, from neurons.
Tay-Sachs disease is a rear inherited disorder that affects the nerve cells (neurons) in the brain as well as the spinal cord. This disease is an autosomal recessive genetic disorder rather than a sex-linked disorder like some think. In order to inherit Tay-Sachs disease, the gene must be inherited by both parents (Gravel, 2003). If the gene is inherited only by one parent, then the individuals will only be a carrier and has the potential of passing on this disease to their children. The odds of inheriting Tay-Sachs disease if both parents are carriers are 1-4 (25%). The chromosome responsible for the abnormality or mutation that causes Tay-Sachs disease is chromosome 15. Chromosome 15 is the one that codes for production of the enzyme hexosaminidase A (Hex-A) (Gravel, 2003).

Nature does not simply determine our physical traits. In Alina Tugend’s article, “For the Best of the Best, Determination Outweighs Nature and Nurture,” Tugend explores the interaction of nature and nurture when it comes to talent. Tugend states that “’genetics influence how quickly and how well a person can master the expertise necessary to perform at world-class levels’” (Tugend 7). Nature influences our abilities or our capacity to do something. If nature can determine how quickly someone can develop a talent, then it does not play such a minimal role in our actions. Zoologist Matt Ridley argues that is nature via nurture in his article “What Makes You Who You Are.” Ridley states that “[genes] are both the cause and the consequence of our actions” (Ridley 5). Our genes and our actions are more connected than we thought. Genes can produce actions and our actions affect which genes are active in our lives. Nature greatly influences our behavior, but it is not all nature.
The issue of whether or not criminal or aggressive behavior and violence is caused by biological or environmental factors has proven to be one that has caused a dispute for many years now. The biological or genetic factor of violent/criminal or aggressive behavior is certainly a much talked about topic. The idea that certain individuals could be predisposed to violence is something definitely deserving of doing research about. The nature vs. nurture topic has been a continuing debate for many aspects of human behavior, including aggression/violent behavior and criminal behavior. There have been many studies indicating that chemical relationships between hormones and the frontal lobe of the brain may play a key role in determining aggressive behavior as well as genetics, while other studies have explored environmental and social factors that have been said to control patterns in human aggression. Aggressive/violent behavior can’t be answered directly if it is caused by either nature or nurture; instead it is believed that both cause it.
...hich inherited traits, such as those for genetic disease, can be tracked over generations. Throughout out the course of human development, scientists will continue to find new new ways to help the human race through the discovery of the human gene inside of each of us, its uses, as well as complications, that can help the survival of our species.
Every individual has a biological influence on their development; two individuals combine their genetic information to create a new organism, carrying biological predispositions that will shape their expressed behaviors and characteristics. However, Susan Griffin, author of the essay “Our Secret,” argues that while genetic influences are significant, they are not the sole contributors to an individual’s development. Throughout her essay, Griffin reveals to her readers that the presence of external, uncontrollable factors from an individual’s environment can be equally influential as they diverge the individual off of the predetermined path of life created by biological factors.
The study of the causes of substance abuse has been conflicting many people for a long time. There are two causes of substance abuse that have been argued for many years. The first cause is believed to be environmental. The second cause is a genetic cause that leads people to turn to drugs and alcohol. In “Touch of Grey” Lanthrop comes to the conclusion that his substance abuse issue posses both genetic and environmental causes. This argument is specifically compelling because he uses research and a personal statement to prove his findings. While environmental issues have a large impact on substance abuse, genetics have the greatest impact on substance abuse.
As a mother, I am shocked and dismayed by the general acceptance of the myth of genetic determinism. One's environment, including people one interacts with, has an undeniable influence on how one develops. Nonetheless, many scientists disregard the impact of environment on one's intelligence. I do not deny that one's biology is a crucial part of one's identity. Inheritance of physical traits is obvious. Children often look "just like" their father or mother, or another relative. One's genes determine eye and hair color, height and body build. I believe, however, that what makes us human is not something that can be found in...
Inheritance, by Sharon Moalem, is a nonfiction novel that elaborates on what makes us who we are and why. Moalem states that even before we are born, our genes set up determines our lives. Our genes are adaptable sequences that can be altered by instances of trauma, simple dietary change, or just a small indiscretion. Through our experiences, our genes are changing and consequently limiting us. We have an unwavering predictable matter of the genes we have inherited from previous generations. Our future children could inherit many of our specific genes, good or bad. Even if our inherited
The distinction between nature versus nurture or even environment versus heredity leads to the question of: does the direct environment or the nature surrounding an adolescent directly influence acts of delinquency, later progressing further into more radical crimes such as murder or psychotic manifestation, or is it directly linked to the hereditary traits and genes passed down from that individual adolescent’s biological parents? To answer this question one must first understand the difference between nature, nurture, environment, and heredity. Nurture, broken down further into environment, is defined as various external or environmental factors one is exposed to which can be more specifically broken down into social and physical aspects. Nature, itself broken down into heredity, is defined as the genetics and the individual characteristics in one’s personality or even human nature.
Genetics is the passing of characteristics from parents to offspring through genes. Genes are information
Genetics is a scientific discipline that deals with how individuals inherit their physical and behavioral attributes. Generally, genetics is a branch of biology that deals with the science of heredity, genes, and differences in living organisms. It’s the process with which a child inherits traits from his/her parents and the molecular organization and function of genes. The question of what determines the development of a child has been an issue that has attracted considerable concerns and debates across educators, biologists, and psychologists. This issue has attracted huge concerns because it’s impossible to explain each and every factor that eventually determines who a child becomes. Notably, the development of a child involves a mix of various influences such as parenting, genetics, individual experiences, family relationships, friends, and school. One of the most important influences on a child’s development and growth is genetics, which primarily is the process of traits inheritance from parents to offspring.
Height, hair color, eye color and sex are just a few examples of ways our DNA has shaped us. But could it be possible that our DNA also effects the way we behave in society. It is possible that genetics effect us is more ways that we may have imagined. Dr. Peter B. Neubaur believes that shyness, eating disorders, obsessive behavior and psychological illness can all be traced back to our genetics. Sexual orientation is also believed to be derived from genes in our body which determine what sexual preference we prefer. Violence and other types of crimes can be linked back throughout a person’s lineage to witness that other family members have been committed similar crimes without ever meeting one and other.
Undoubtedly heredity is responsible for the growth of a person from the fetus till the end, for the colour, sex and all other distinguishing traits and features. However it cannot totally develop a person into an intelligent knowledgeable person. This is only possible through the exposure, experiences that a person gets from his surroundings, his environment. Man being the product of evolution has greater capacity of adaptability and he can adjust himself with any environment. Heredity and environment thus are equally important and together they determine our
