To increase the complexity of the genetics, problem, you are going to add another trait. We will still work with purple (P) and
yellow (Y) seeds, but we're adding seed shape. Smooth (S) is dominant to wrinkled (s). If you have a parent generation that is homozygous at both loci, and one parent has purple smooth seeds, and the other has yellow wrinkled seeds, what is the genotype of the yellow parent?
we have the yellow seeds with the Y allele and the purple seeds with the P allele.
the next characteristic is that they are wrinkled named with the s allele and smooth with the S allele
the parents are homozygous, which indicates that in each loci there are identical alleles, in which one of the parents has smooth purple seeds manifesting with the PPSS phenotype and the second father will have wrinkled yellow seeds with the YYss phenotype, thus the father will have the PPSS phenotype
