PPT-Human chromosome 2 Mapping

Linkage One of the main observations from Mendel was independent assortment alleles of different genes will get assorted mixed up independently of one another We already showed that the genes are carried by the linear chromosomes.

Are these differences due to differences in the magnitude of the effects (quantitative)?. e.g. Is the contribution of genetic effects greater/smaller in males than in females?.
