Answer:

B

Explanation:

Gene (c) is located in autosomes and is a recessive allele.

Chickens with two alleles c has short-legged phenotype in heterozygotes (Cc). Those with the recessive genotype (cc) are also short-legged, as they have two alleles (c).

Therefore, normal legs are repoduced by the homozygous dominant genotype (CC), when no allele (c) is available.

The answer is B.
