The dominance law was proposed by a famous biologist Mendel that stated: When parents with pure, contrasting traits are crossed together, only one form of trait appears in the next generation. Dihybrid: the offspring of two parents that only differ at two specific gene loci. In watermelons, solid green rind color (G) is dominant to stripes (g). Cross Multiplication Calculator Genetics with Drosophila F1 Crosses And due to this shuffling, new gametes are formed that are quite different and this is what makes offspring different from his/her parents and siblings.
