Question

in a group of chickens, some individuals have white legs and others have yellow legs. in this group, the gene for the leg color trait has two alleles. the allele for white legs (l) is dominant over the allele for yellow legs (l). this punnett square shows a cross between two chickens. how many boxes represent offspring with white legs?

Explanation:

Step1: Identify dominant allele

White legs (L) is dominant over yellow legs (l). So genotypes LL, Ll show white legs.

Step2: Count boxes with LL or Ll

Punnett square has 4 boxes: LL, Ll, Ll, ll. Boxes with LL or Ll: 3 (LL, Ll, Ll).

Answer:

3
