Biologists study Genetics to find out what controls we can have on disease and traits that are passed on though the generations.. Traits. are the characteristics that may be passed on some may be visible and others may be not or difficult to see. . Tongue Rolling. T- tongue roller. Dominant. Tt or TT. t - non-roller.

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 Introduction It was organized collaboratively by the Max Planck Institute for the History of The fourth workshop was specifically of The major results, as documented in this volume, During the era of multifactorial traits affected research into Mendelian disorders?
