In the Purple Penguin,an Allelic Series Occurs at the P

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

A) 2 dark:1 light:1 very pale.
B) 2 dark:1 medium:1 light.
C) 1 dark:1 medium.
D) 1 dark:1 medium:1 light:1 very pale.
E) 1 medium:1 light.
