Document Summary
Introduction: first insights into mechanism for inheritance of biological traits . Mendel"s seven monohybrid crosses of the garden pea (pisum sativum). In each case, pollen derived from plants exhibiting one trait was used to fertilize the ova of plants exhibiting the other trait. In the f1 generation, one of the two traits was exhibited by all plants. Individuals are shown in rectangles, and gametes are shown in circles. In (a), the tall parent is homozygous, but in (b), the tall parent is heterozygous. The genotype of each tall p1 plant can be determined by examining. 8: computation of the combined probabilities of each. The f1 heterozygous plants are self-fertilized to produce an f2 generation, which is computed using a punnett square. Both the phenotypic and genotypic f2 ratios are shown. This method is based on the expected probability of occurrence of each phenotype. 2c values for selected values of d f and.
