Begin Results Section with a Little Overview RESULTS The ratios of dominant to recessive forms were remarkably consistent in each of the first generation offspring of the monohybrid and dyhybrid crosses. The 3:1 ratio (dom:rec) in monohybrid crosses was expressed as a 9:3:3:1 ratio in the dyhybrid crosses. There was no evidence of blending and no evidence of an effect of gender on the outcome of any of the crosses. Monhybrid crosses Each of the initial seven monohybrid crosses resulted in plants that exclusively expressed the dominant form of each trait. The recessive form appeared only in later generations. This constituted the definition of dominant and recessive froms. When the monohybrids were allowed to self-fertilize, dominant and recessive forms were expressed in a ratio of approximately 3:1 for each of seven traits (Table 1) …. more detail…. Self fertilization among the first generation offspring of the initial monohybrid crosses revealed a pattern among the offspring that reflect heterogeneity among the parent plants…. (this is about the 2:1 ratio of constant dominant to hybrid dominant… Dyhibrid crosses
