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.
A basic principal of biology states that the behavior of chromosomes during the meiosis process can account for genetic inheritance patterns. There are many reasons for genetic disorders. To start it is important to understand what a genetic disorder is. It is a mutation in the genetic material of a person. The mutant gene is transmitted thru birth.
Offspring inherit genes that contain specific traits that can be genetic disorders, natural talents, or physical characteristics from their parents. Genes are located in chromosomes. The human body contains two sets of 23 chromosomes which a set from each parent. Therefore a child inherits a set of genes from each parent and even if a trait isn’t observed it still can be passed to the next generation. This genetic makeup means that each individual have two copies one from their mom and one from their dad.
The human body is made up of millions of cells, each containing heritable information in the form of DNA. This DNA contains genetic information known as genes which can be passed down from one generation to the next, and is expressed as the numerous traits we see in various organisms today. Genes can therefore be seen as the unit of inheritance from parent to offspring (Campbell undated). In the following essay I will discuss the reproductive process and how the passing of genes leads to offspring having similarities to their parents. In addition I will look at the two methods of reproduction and how each leads to similar or different traits expressed in the offspring, as well as the evolutionary significance of genetic variation within a population.
Even though a child inherits several genes from the two parents, his/her ability to express these factors is dependent on gene-gene and gene-environment interactions. Therefore, a child’s growth and development is not only influenced by hereditary factors but also determined by environmental influences.
A 9:3:3:1 ratio is typical for a dihybrid cross between two heterozygous individuals. Conclusion: Inheritance is the means by which certain traits are passed down from one generation to the next. By applying Mendel’s law of dominance it is possible to choose genetic traits in parents to produce offspring that carries the desired trait. It is also beneficial in determining the likelihood of passing down genetic diseases from one generation to the next. However environmental factors and mutations can increase or decrease the probability of inheriting particular genes.
In an attempt to answer this questions various researchers have come up with contradicting ideas in determining if our characteristics and behaviors are primarily due to genetics or the environment in which we live. There are many issues and aspects of lives that influence us daily. These aspects create different situations that lead us to determine our path and destiny. To begin with, our similarities to our parents in personality is entirely genetic, we are born with a set of genes that never change. For instance, during conception two set of genes joint together into one and from that moment D.N.A starts to determine certain characteristics that we possess.
The mental skills of a sport are just as important as the physical skills. All professional athletes use sports psychology. “If they aren’t currently using it, it’s almost guaranteed they’ve used it in the past, even if they are unaware they have” (Davis, Stephens, The Exploratorium 129). It’s hard to find an experienced athlete who hasn’t used sports psychology, because without it, they probably wouldn’t be where they are. The use of sports psychology is a crucial step to becoming a successful athlete.
Many life lessons can be taught through sports. Children can learn the importance of work ethic, working with others, perseverance, and the list goes on. There are studies that have shown that kids who are involved in athletics are more successful in the business world. It is only when parents turn the sporting events into an ultra-competitive requirement for their child that it can become detrimental. The lessons that sports teach kids about real life is one of the greatest benefits that can be gained from sports.
Genetics helps determine the role of DNA in the inheritance of genetic traits. Genetics is the study of heredity. Offspring obtain genes from parents by a process known as inheritance. Genes(segments of DNA on a chromosome) are the hereditary units of coded information that parents endow to their offspring. The genes in our body program specific traits as we develop from fertilized eggs into adults.
