Question

In rabbits, the gene for grey fur (G) is dominant over that for black fur (g). In a litter, if 50% rabbits are grey, then the possible parental cross combination is

GG x Gg

gg X gg

GG x GG

Gg x gg

Solution

Gg x gg

When heterozygous grey individuals (Gg) are crossed with homozygous black individuals (gg), then grey and black individuals will be obtained in equal ratio. It is a type of test cross and can be illustrated as:
