PPT-Allele Expression Crosses between pure breeding individuals that differ in one or two

This may be because The genes are linked or sexlinked Allele expression not always as simple as dominant alleles overriding recessive ones Alleles of a single gene may interact together and give rise to phenotypes that are dissimilar to both of the parents.
