WebThe consistency of gametic phase was defined by the Pearson correlation of signed LD (measured by r) values between two populations [Line1 vs. Line2; Line1 vs. F1 (F1-1, F1-2, F1-3, and F1-4); Line2 vs. F1 (F1-1, F1-2, F1-3, and F1-4)]. WebIt was also observed that when two such dominant alleles or recessive alleles come from different parents, they tend to remain separate. This was termed as gametic repulsion. In Bateson’s experiment, in repulsion phase, one parent would have blue flower and round pollen (BBII) and the other would have red flower and long pollen (bbLL).
