In roosters, the allele for rose comb (R) and the allele for pea comb (P) producea condition called walnut comb whenever they occur together (R_P_). It does notmatter what the 2nd allele is. Individuals that have the homozygous recessivecondition for both sets of alleles (rrpp) are single-combed.a. Give the phenotypes of both the F1 and the F2 of a cross between a purebreeding rose comb rooster (RRpp) and a hen with alleles for pure-breedingpea comb (rrPP).

In roosters, the allele for rose comb (R) and the allele for pea comb (P) producea-example-1

Answer:

F1 generation phenotype- all will have a WALNUT COMB.

Explanation: The resulting offspring from the cross between these genotypes RRpp X rrPP, are:

RrPp, RrPp, RrPp, RrPp

Answer:

F2 Phenotype:

9/16- walnut comb

3/16- rose comb

3/16- pea comb

1/16- single comb

Step-by-step explanation:

From the result of the genotype of the F1 generation, RrPp XRrPp, these are the result.
