Genetics and Heredity essays

Genetics and Heredity essays ?What are genetics? It is the study and the variation of inherited characteristics that make up new life. Every child inherits genes from both of their biological parents. Some of these traits may be physical; hair, eye color or skin colors, etc. On the downfall some genes might carry certain diseases or disorders. Each gene is a piece of genetic information and all DNA in the cell make up the human genome. The wonderful thing about genetics is the technology that has been made for it and how advanced it is to now do what ever it takes to fix the unborn. Genes generally express their functional effect through the production of proteins, which are complex molecules responsible for majority of functions in the cells in the body. Heredity is a biological process where a parent passes certain genes onto their children or offspring's which all falls under the study of genetics. Genetic information with genes from their parent lies within the cells nucleus of each living cell in the body. The genes will be rested inside the chromosomes in the human body. In the body, we have up to 46 chromosomes divided equally between the mother and father. A chromosome is an organized structure of DNA and protein that is found in cells that plays a major role in genetics. There are about 20,000 genes located on one of the 23 chromosome pairs found in the nucleus. Chromosomes are the structures that hold our genes. Genes are the building blocks of heredity; every child inherits genes from both of their biological parent. Some traits are physical for example; eye, hair and skin color will be brought down from the parent to the offspring. The down side of inheriting different genes is that the offspring may inherit some disorders or disease. A single gene disorder is where a mutation affects one gene, for example sickle cell anemia. Another disorder that can occur from genes is a chromosomal disorder is where the chromosomes or part of it is missing o...
