Question

in a group of rainbow trout, some individuals have a greenish - brown body and others have a blue body. in this group, the gene for the body color trait has two alleles. the allele b is for a greenish - brown body, and the allele b is for a blue body. a certain rainbow trout from this group has a greenish - brown body. this trout has one allele for a greenish - brown body and one allele for a blue body. based on this information, click the blue words to correct any errors in the text. this rainbow trouts genotype for the body color trait is a greenish - brown body. this rainbow trout is heterozygous for the body color gene. this rainbow trouts genotype for the body color gene is bb.

Explanation:

1. The first statement incorrectly labels a phenotype (greenish-brown body) as a genotype. Genotype refers to the genetic alleles, so "a greenish-brown body" should be replaced with "Bb".
2. The second statement is correct: having one dominant and one recessive allele (B and b) means the trout is heterozygous.
3. The third statement is correct: the trout has one B allele and one b allele, so its genotype is Bb.

Answer:

Corrected first statement: This rainbow trout's genotype for the body color trait is Bb.
Unchanged second statement: This rainbow trout is heterozygous for the body color gene.
Unchanged third statement: This rainbow trout's genotype for the body color gene is Bb.
