Content: Although the importance of genes cannot be overemphasized, however, they only make up a small percentage of all the DNA. Each individual has a specific number of chromosomes which are 23 in number. On each chromosome are found a particular set of genes and they have specific locations where they are found. During fertilization and eventual fetal development, these genes are passed down to an offspring and as such we can say that the child inherits his genes from his parents. There are two copies of each chromosome that are found in one individual and as such two copies of a particular gene. During copulation and fertilization, each parent gives up one pair of their gene to their offspring and as such, every baby grows up with two sets of genes. These babies grow and pass on two sets of genes to their offspring and the cycle continues on. The purpose of a gene is to carry out specific instructions for the body. Some genes do multitask by carrying out more than one instruction. These instructions that the gene carry out is mostly towards the formation of a particular protein and there are many types of proteins that carry out different functions.
