Number of genes depends on the DNA number in a particular cell and the numbers vary widely among organisms. Therefore, a gene or set of genes determines the differences between individuals within a species as well as differences between species.Human genome consists of over 20,000 genes, and certain genes of humans are also found in other animals and even in certain plants.umber of genes depends on the DNA number in a particular cell and the numbers vary widely among organisms.
