Question

a. What is the expected genotypic ratio of the offspring when a homozygous red fluorescent male fish is crossed with a heterozygous female fish? b. What is the anticipated phenotypic ratio of the offspring resulting from the cross between a homozygous red fluorescent male fish and a heterozygous female fish?

Answer 1

The expected genotypic ratio is 1:1 (RR:Rr) and the anticipated phenotypic ratio is 1:1 (red:non-red).

Step-by-step explanation:

When a homozygous red fluorescent male fish is crossed with a heterozygous female fish, the expected genotypic ratio of the offspring would be 1:1 for the genotype RR:Rr. This means that half of the offspring will be homozygous for the red fluorescent trait (RR) and the other half will be heterozygous (Rr).

The anticipated phenotypic ratio of the offspring resulting from this cross would be 1:1 for the phenotype red:non-red. This means that half of the offspring will exhibit the red fluorescent phenotype and the other half will not.
