Heredity is the cause of similarities between individuals. This is the reason that brothers and sisters with the same parents resemble each other and with their parents. Variation is the cause of differences who do resemble each other are still unique individuals. Thus, we have no trouble in recognizing the differences between sisters, for example, and even ‘identical’ twins are recognized as distinctive individuals by their parents and close friends. . 1 Human Population Genetics Mendelian Inheritance in Man Paper No. : 0 8 Human Population Genetics Module : 0 6 Mendelian Inheritances in Man Prof. Anup Kumar K apoor Heredity /Genetics Gregor Mendel was a n Augustinian friar who gained posthumous fame as the founder of the modern science of genetics .
