In the purple penguin,an allelic series occurs at the p locus on an autosome.All alleles affect the color of feathers: pd = dark-purple,pm = medium-purple,pl = light-purple,and pvl = very pale purple.The order of dominance is pd> pm> pl> pvl.If a pl/pvl female is crossed to a pd/pmmale,the ratio of phenotypes expected among the baby penguins would be:
