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. chirpie, a chicken from this group, has yellow legs. chirpie has two alleles for yellow legs. based on this information, click the blue words to correct any errors in the text. chirpies genotype for the leg color trait is yellow legs. chirpies phenotype for the leg color gene is ll. chirpie is homozygous for the leg color gene.

Explanation:

1. For the first sentence: Genotype refers to the genetic makeup (alleles), while "yellow legs" is a phenotype (physical trait). Since Chirpie has two alleles for yellow legs (ll), the genotype should be \( ll \), and the phenotype is yellow legs. So we correct "genotype" to "phenotype" and "yellow legs" to \( ll \) (or just note the correction: the first "genotype" should be "phenotype" and "yellow legs" should be "ll" as genotype).
2. For the second sentence: Phenotype is the observable trait (yellow legs), and \( ll \) is the genotype (genetic makeup). So we correct "phenotype" to "genotype" and "ll" to "yellow legs" (or note: the second "phenotype" should be "genotype" and "ll" should be "yellow legs" as phenotype).
3. For the third sentence: Chirpie has two identical alleles (two alleles for yellow legs, so \( ll \)), which means it is homozygous. So this statement is correct, no correction needed for "homozygous".

Answer:

1. Correct the first sentence: Change "genotype" to "phenotype" and "yellow legs" to \( ll \) (or state the corrected sentence: "Chirpie’s phenotype for the leg color trait is yellow legs." and "Chirpie’s genotype for the leg color trait is \( ll \)").
2. Correct the second sentence: Change "phenotype" to "genotype" and "ll" to "yellow legs" (or state the corrected sentence: "Chirpie’s genotype for the leg color gene is \( ll \)." and "Chirpie’s phenotype for the leg color gene is yellow legs.").
3. The third sentence ("Chirpie is homozygous for the leg color gene.") is correct, no changes needed.
