Question

5. In rainbow trout, you are studying scale color and patterning. You have identified two genes:
R = rainbow scale color, where loss of function confers a "gray-scale" color phenotype.
S = stripe pattern, where loss of function confers a spotty pattern phenotype.

You cross a rainbow horizontal striped fish to a gray spotty fish with the following strange result:
(Female) RRSS x (male) rrss -> RrSs with phenotype gray and striped.  

Which parent was the recessive gray allele inherited from, and what can be said about which parent is imprinting which gene? Female; Male imprints R Female; Female imprints R Male; Female imprints R Female; Male imprints S Male; Male imprints R Male; Female imprints S 6. In a related species of rainbow trout, You have identified the same two genes:
R = rainbow scale color, where loss of function confers a "gray-scale" color phenotype.
S = stripe pattern, where loss of function confers a spotty pattern phenotype.

However, this time You cross pure lines of rainbow striped fish to pure lines of gray spotty fish, resulting in:
(Male) RRSS x (Female) rrss -> RrSs with phenotype rainbow and spotty.  

Which parent was the recessive spotty allele inherited from, and what can be said about which parent is imprinting which gene? Female; Male imprints S Male; Female imprints R Female; Female imprints S Male; Female imprints S Female; Male imprints R Male; Male imprints S 5.
