Follow-Me – . iQuiz. Q. What term is used to describe differences within a population with respect to features such as height?. 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. . Chapter 16.1. Life. ’. s Operating Instructions. In 1953, James Watson and Francis Crick introduced an elegant double-helical model for the structure of deoxyribonucleic acid, or DNA. Hereditary information is encoded in DNA . What Are the Molecules of Heredity?. . . After scientists became aware of the differences in amino acid sequences, their next quest was to determine how cells know which proteins to synthesize out of the extremely large number of possible amino acid sequences. The answer is that an individual gets the information from its parents through .
