Aleksandr [31]

Answer:

Option B, Rr pp × rr Pp

Explanation:

Given

Walnut Comb is produces when  one dominant allele R is present at one gene locus and at least one dominant allele P is present at a second gene locus - R* P*

Rose Comb - at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus - R* pp

Pea comb - two recessive alleles are present at the first locus and at least one dominant allele is present at the second  - rr P*

Single comb - two recessive alleles are present at the first and the second locus  - rrpp

Parent are rose combed and pea combed

For being rose genotype must be R* pp

and for being pea combed genotype must be rr P*

Rr pp x rr Pp

will  produce

Walnut comb  with genotype Rr Pp

Single comb  with genotype rrpp

and pea comb  with genotype rrPp

Hence, option B is correct
