Multiple Alleles

In mice, there are several alleles at the C locus that control intensity of pigmentation in the hair. The designations for alleles and phenotype are:

C       Full color
cch       Chinchilla
ce       Extreme dilution
ch       Himilayan (pigment restricted to extremities)
cp       Platinum
c       Albino

The alleles are listed in order of dominance with C most dominant.

What is the progeny ratio for each of the following matings:

Choose a mating:

Ccp x cpc

cchcp x cech

cchch x cchch
