Question

Options

• RrYy

• RRYY

• RRYy

• RRyy

Answer 1

If the gametes of an individual are RY and Ry only, then the genotype of the same individual will be RRYy.

Explanation:

Both gametes carry R, so the individual must be homozygous RR at that locus. The gametes differ at the second locus (Y or y), so the genotype is RRYy.
