Loppins Can Be Purple or White,and This Phenotype Is Inherited

Essay

Loppins can be purple or white,and this phenotype is inherited as a simple dominant/recessive trait with complete penetrance.In females,purple is dominant over white,while in males the opposite is true.If you cross a white female to a purple male,and then you "self" the F₁ (i.e.,you cross brothers and sisters)what phenotypic ratios would you expect in the F₂? Assume that you always get a 1:1 ratio of males : females.
