Question

in a group of guppies, some individuals have a gray body and others have a golden body. in this group, the gene for the body color trait has two alleles. the allele b is for a gray body, and the allele b is for a golden body. wanda, a guppy from this group, has a gray body. wanda has two alleles for a gray body. based on this information, click the blue words to correct any errors in the text. wanda’s genotype for the body color trait is a golden body. wanda is heterozygous for the body color gene. wanda’s phenotype for the body color gene is bb.

Explanation:

1. For "Wanda’s genotype for the body color trait is a golden body": Genotype refers to the genetic makeup (alleles). Wanda has two gray body alleles (BB), so "golden body" (a phenotype) is wrong. It should be "BB" (or "homozygous gray" conceptually, but allele - wise BB).
2. For "Wanda is heterozygous for the body color gene": Heterozygous means having two different alleles (e.g., Bb). Wanda has two B alleles (homozygous), so "heterozygous" is wrong. It should be "homozygous".
3. For "Wanda’s phenotype for the body color gene is Bb": Phenotype is the observable trait (gray body), while Bb is a genotype. So "Bb" is wrong. It should be "gray body".

Answer:

• Wanda’s genotype for the body color trait is $\boldsymbol{BB}$ (or "homozygous gray" - but allele - specific correction is BB).
• Wanda is $\boldsymbol{homozygous}$ for the body color gene.
• Wanda’s phenotype for the body color gene is $\boldsymbol{gray\ body}$.
