In rats, two genes each with two alleles (A,a and R,r) interact to produce the following phenotypes

 In rats, two genes each with two alleles (A,a and R,r) interact to produce the following
phenotypes:
A_R_ : grey
A_rr  : yellow
aaR_ : black
aarr : cream
These phenotypes require that another gene with the dominant allele C be present since cc
individuals are albino. All genes assort independently. Two different albino lines were each
crossed with a true-breeding grey strain and all produced grey F1 progeny. The F2 were as
follows:
Albino
Line Grey Yellow Black Cream Albino
1 48 0 0 0 16
2 292 87 88 32 171
What is the most probable genotype of each albino line
