    Basically, male sex cells are determined by the XY combination; heterosomes, (while the female sex cells by the XX). Since it is the Y chromosomes present in the father only that determines the male sex of the child and therefore the proof of paternal inheritance ' the women in the class will not be able to participate in the inheritance analysis. Due to lack of the Y - chromosomes.
