What genotypes and phenotypes would be expected from the following cross??? () means its above previous letter

1. Cc(h) X c(ch)c
2. Cc X Cc(ch)
3. c(ch)c(h) X cc

Genotypes: Phenotypes:
CC, Cc(ch), Cc(h), Cc =Full Color
c(ch)c(ch), c(ch)c(h), c(ch)c =Chinchilla
c(h)c(h), c(h)c =Himilayan
cc =Albino

Start by putting the gametes from the parents on a Punnett square to get the genotypes. Your key tells us that C for full color is dominant to any c. If there's no C, then ch for Chinchilla is dominant to Himalayan and albino, h for Himalayan is dominant to albino, and c for albino is recessive to absolutely everything.

1. Cc(h) X c(ch)c
Offspring: Cc(ch), Cc, c(h)c(ch), c(h)c
2 full color: 1 chinchilla: 1 Himalayan

2. Cc X Cc(ch)
Offspring: CC, Cc(ch), cC, cc(ch)
3 full color: 1 Chinchilla

3. c(ch)c(h) X cc
Offspring: c(ch)c, c(ch)c, c(h)c, c(h)c
1 Chinchilla: 1 Himalayan
