Pure-breeding strains of two mutant panthers were developed in different zoos. Neither mutant makes hair pigment, so the hair is transparent and the fur appears to be pink rather than the normal black. When each mutant was crossed to homozygous black panthers, the F1 were always black no matter which parent was pink. The mutants were called pink-1 (pk-1) and pink-2 (pk-2) for convenience, but it was not known whether they were mutations of the same gene or mutations in different genes.
C: What would be the result of a cross between pink-1 and pink-2 if the two mutations were in different genes? Include the genotypes of the panthers in your answe D: What phenotypic ratio would occur in the F2 generation if the two mutations were in different genes
