Answer:
The phenotypes will be -
AaBbcc - Albino,
AaBBCC - Agouti Black
Aabbcc - Albino
AAbbCc - Agouti Brown
aaBbCc - Solid color, Black
AABBcc - Albino
Explanation:
The C/c gene is epistatic to both the A/a and B/b genes, any offspring with the cc allele combination will be albino. Otherwise, the A/a and B/b genes are expressed normally.

Answer:
Phenotype frequency ( widow's peak ) = 0.5
Phenotype frequency ( straight hairline ) = 0.5
Genotype frequency ( Ww ) = 0.5
Genotype frequency (ww) = 0.5
Allele frequency ( W ) = 0.25
Allele frequency ( w ) = 0.75
Explanation:
Given, Widow's peak (W) is dominant over straight hairline (w).
Parent 1: heterozygous dominant = Ww
Parent 2: homozygous recessive = ww
When Ww X ww :
W w
w Ww ww
w Ww ww
Half of the offspring are Ww and other half are ww so genotype frequency of Ww is 0.5 and of ww is 0.5. Phenotype ratio for widow's peak (Ww) is 0.5 and for straight hairline (ww) is 0.5.
Allele frequency = Number of that allele / Total number of alleles
f(W) = 2 / 8 = 0.25
f(w) = 6 / 8 = 0.75
