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 blue body. this rainbow trout is heterozygous for the body color gene. this rainbow trouts genotype for the body color gene is bb.

Explanation:

1. Genotype refers to the genetic makeup, not the physical trait (phenotype). The phrase "a blue body" is a phenotype, so it is incorrect here. The correct genotype for the trout with one B and one b allele is Bb.
2. A heterozygous organism has two different alleles for a gene. Since the trout has B and b alleles, this statement is correct.
3. The trout has one B (greenish-brown) allele and one b (blue) allele, so its genotype is indeed Bb, making this statement correct.

Answer:

1. Corrected first sentence: This rainbow trout's genotype for the body color trait is Bb.
2. Second sentence (no correction needed): This rainbow trout is heterozygous for the body color gene.
3. Third sentence (no correction needed): This rainbow trout's genotype for the body color gene is Bb.
