Recommended: the importance of DNA in the human cell

Heredity is the spread of genetic characters from parents to children, this process depends on the separation and recombination of genes during meiosis (a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell) and fertilization and it results a new human that have some similar characteristics from the parents.

Gregor Johann Mendel was born in 1822 and died in 1884 he was a German scientist and was the founder of the new science of genetics. Mendel made and experiment on the pea plant and his result was that the inheritance of certain traits in pea plants follows particular patterns, now referred to as the laws of Mendelian inheritance. Heredity is important because we take our characteristics from our parent that’s why we have similar traits with them for example, eye color, hair type, or skin color. Heredity wouldn’t work without these three important factors, the first factor is called cells and it is the basic structural, functional and biological unit of all known living organisms, inside the cell there is something called a nucleus it contains DNA inside it. The second factor is called DNA and it is the hereditary material in humans and approximately all other organisms. In a person’s body all the cells have the same DNA. The third factor is called genes and it is a unit of heredity which is transferred from a parent to children and is held to determine some characteristic of the young.

Now, I will start talking about Mendel experiments’ I will start talking about the pea experiment that Mendel did. Mendel discovered that certain traits show up in offspring plants without any combination of parent characteristics. For example, the pea flowers are either pur...

    Genetics has given us important results with regards to knowing why certain organisms and their expressions are the way they are and how some expressions are suppressed due to those particular expressions being recessive. The reason is because genetics is the study of genes and the effects of it to organisms.

    No one knew how heredity (passing traits) worked until Gregor Mendel, an Austrian monk, crossbred pea plants in his monastery kitchen garden in 1865. In 1869, gene-hunters found rod-like shape in the nucleus of cells that turned red when dye was added. They named this “Chromosome”, from a Greek word, chroma for color. They also went deeper into the cell and discovered a wispy microscopic thread within the chromosomes, which they named DNA. There were several scientists who did not know about Mendel’s breakthrough at the time, but then in 1900, they rediscovered his experiment and old journal copies.

  • Inheritance: How Our Geness Change Our Lives Change Our Genes, By Sharon Moalem

    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

    Gregor Mendel was born into a German family, as a young man Mendel worked as a gardener and studied beekeeping. In his later life Mendel gained his fame as the founder of the modern science of genetics. The research that was his claim to fame was his pea plant experiment. Mendel looked at seven different characteristics of the pea plants. For example with seed colors when he bred a yellow pea and green pea together their offspring plant was always yellow. Though, in the next generation of plants, the green peas reemerged at a 1:3 ratio. To explain what he had discovered, Mendel put together the terms “recessive” and “dominant” in reference to specific traits. Such as, in the previous example the green peas were recessive and the yellow peas

  • Gregor Mendel's Theory Of Heredity

    265 Words  | 1 Pages

    Heredity was a concept that little was known about before the 20th century. In that era, there were two main concepts that most followed about heredity. First, that heredity occurred within a species, and second, that traits were given directly from parents to offspring. These ideas led people to believe that inheritance was the result of a blend of traits within a fixed, unchanging species. In 1856, Gregor Mendel began his experiments in which he would discover the basic underlying principles of heredity.

    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.

    Gregor Mendel, born as Johann Mendel, is considered to be one of the most significant historic scientist of all time.

He is remembered for paving the way for scientists and future generations to come. Unfortunately, Mendel’s work went unnoticed until 16 years after his death and 34 years after he published his research. Though Mendel lay covered in his grave, his work would eventually be uncovered. Although Mendel was not there to see it,

  • The Role of Genetics on Development

    677 Words  | 2 Pages

    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, Child Growth and Development

    854 Words  | 2 Pages

    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.

    The study of nature development refers to the inherited characteristics and tendencies, these are genetic, and these which are inherited help influence the development through childhood. Some inherited characteristics appear in virtually everyone, For instance, almost all children have the capacity to learn to walk, understand language, imitate others, use simple tools, and draw inferences about how other people view the world. The coding of genes in each cell determine the different traits which we have, more dominantly on the physical attributes like eye colour, hair colour, ear size, height, and other traits. However, it is still not known whether the more abstract attributes

    Heredity is one of the important factors that contribute to the formation of human personality. It refers to the biological process of transmission of certain biological and psychological characters from parents to children through genes. This genetic inheritance received by every individual at the time of conception is referred to as Heredity. As such the physical character of a person, like height, weight, color of skin, eyes, hair, social and intellectual behavior are all determined by heredity. It influences man’s social behavior too.
