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 can affect a person’s physical and mental health. There are a number of genetic/ chromosomal disorders such as sickle cell disease, Tay Sachs Disease, Huntington’s disease, Turner syndrome and Down syndrome. There is also evidence that genetics contributes to depression, autism, bipolar disorder, schizophrenia and other metal disorders. In addition, genetics plays a role in determining the physical make up, psychological make up and mental make up of a child and that is why at times there are certain abnormalities such as Tay Sachs disease.
Tay-Sachs disease also known as GM2 gangliosidosis is a deadly disorder that gradually obliterates the nerve cells both in the brain and the spinal cord. It is a rare autosomal recessive genetic disorder that causes the deterioration of the neurons and the...
