But the fact is, genes determine only so much. Identical twins have identical genomes, yet one may develop juvenile diabetes and the other typically doesn’t. Understanding the role of genes should help pinpoint environmental factors … The genome is a history book showing the entire 6 billion-member human species traces back 7000 generations to a tiny founding population of some 60 000 people. Our species has only a modest amount of genetic variation—the DNA of any two humans is 99.9% identical.ERIC LANDER, HUMAN GENOME PROJECT, 20001 SN - PB - McGraw-Hill Education CY - Sydney, Australia Y2 - 2024/04/18 UR - murtagh.mhmedical.com/content.aspx?aid=1186895730 ER -
