Mendel developed basic principals of heredity with . heredity. 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. . multifactorial traits affected research into Mendelian disorders? Stylianos E. Antonarakis. For about a century, the argument for focusing on rare Mendelian disorders was as follows: Mendelian ph
