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 L is for white legs, and the allele l is for yellow legs. Buddy, a chicken from this group, has yellow legs. Buddy has two alleles for yellow legs. Based on this information, what is Buddy's phenotype for the leg color trait?

Answer 1

Buddy's phenotype is yellow legs, and his genotype is homozygous recessive (ll) for this trait, with both alleles being for yellow legs.

Step-by-step explanation:

Buddy, the chicken with yellow legs, has a phenotype that expresses the leg color trait as yellow. This is the observable characteristic of Buddy's physical appearance. Since we know Buddy has two alleles for yellow legs, and given that leg colors in chickens in this scenario are determined by two alleles (L for white and l for yellow), Buddy's genotype for this trait must be homozygous recessive (ll), with both alleles being the version for yellow legs. The presence of the homozygous yellow alleles (ll) results in this visible phenotype.

Answer 2

Buddy's phenotype for the leg color trait is yellow legs.

Buddy's phenotype for the leg color trait is yellow legs. Based on the information given, Buddy has two alleles for yellow legs. In this case, the allele for yellow legs (allele l) is dominant over the allele for white legs (allele L). So, even though Buddy has two alleles for yellow legs, his phenotype will still be yellow legs.

Buddy, the chicken, has the genotype ll for the leg color trait. The genotype ll indicates that both alleles for the leg color trait are the recessive allele (l) for yellow legs.

In terms of phenotype:

- Phenotype refers to the observable traits of an organism.

- The phenotype for the leg color trait is determined by the genotype.

- In this case, the recessive allele (l) for yellow legs is expressed in Buddy's phenotype.

Therefore, Buddy's phenotype for the leg color trait is yellow legs.
