>>>>>>the father of genetics: johann (gregor) mendel (see fig 10-2) Mendel was a monk who was trained in science at the university of vienna. The realization that both parents contributed to the characteristics of the offspring preceded the work of mendel. The favorite explanation of how this occurred was the blending theory of heredity. Modern genetics began with mendel, and lead to the replacement of the blending theory with the particulate theory of heredity. Mendel developed his theory from the study of the variation of garden peas. The offspring"s traits are some intermediate between the parental types. Unable to explain why characteristics disappear in one generation and. If this was true population would reach a uniform appearance. --traits are the variants of an inheritable feature. For mendel"s pea plants the traits he examined were (see fig. The flowers of the pea plant normally undergo self-fertilization. Mendel started his experiments with true-breeding plant varieties which he hybridized (cross-fertilized)
