उत्तर
When scientists began estimating the number of human genes, they began with a very high figure. i.e. more than 100,000. At that time. the technology For studying human genes was not sophisticated enough and the estimate was more qualitative in nature as it was mainly based on assumptions. With gradual progress of technology and knowledge about human genes, the estimated number began to come down. The present knowledge tells us that total number of genes in humans is between 20,000 to 25,000.
