Human beings are born, formed and changed from one generation to another through genetics. When a baby comes into the world, there is always a lot of excitement and uncertainty about which parent will the baby be? The genes of both parents determine the physical composition of a child and therefore genetics plays a very important role in human development. Genetic chromosomes are distributed equally from parents to the child and play an important role in the child's development. Genes determine the development of a fetus inside and outside the mother's womb. Genes are passed from parents to children and this determines their lifelong development. When a male cell meets a female reproductive cell, they begin 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 will include both genes. From eyes to hair color, genetics play a role in a person's makeup and biological development. Genes can predetermine many different characteristics in human development. Genetics determine simple things like a person's ultimate height. “The entire genetic code of a human being is determined by the unique combination of the mother's single egg and the father's single sperm” (Mossler, 2011). Therefore every person on earth is a combination of his biological parents who in turn are a combination of their biological parents and the chain continues endlessly. Genes are an important basis for how one becomes and how one will develop from childhood to adulthood. Studies have also shown that genetics also plays a role in diseases and illnesses that c...... center of the card...... their genetic material is transmitted as DNA which is the map of the new being unique human that is formed after conception. The genetic material determines specific traits in the newly created life both physically, mentally and emotionally as the individual must take after the mother and father. It can also determine whether a genetic disease will be present in this lifetime in the future. In essence, the role that genetics plays in human development is the instructions by which we are all brought together. Works Cited Champaigne, Neena. (2008). Medical genetics and dysmorphology.
