Offspring in humans get about 80 new mutations that parents never. Polygenic traits shown continuous variation in a population phenotypes. X-chromosome isn"t girly : genes for making uterus are on x and all over the place, nothing specifically pertaining to sex traits lies on x- including autosomes chromosome. Reciprocal crosses illustrate sex linkage in drosophila: + does not mean dominant, it means wild type , not mutant, can be dominant, doesn"t have to be. Alleles of two genes assort independently in dihybrid crosses.
