[QUESTION]What is the expected ratio of offspring with a gray body to offspring with a black body? Choose the most likely ratio.
[OPTIONS](A) 4:0 (B) 1:3 (C) 3:1 (D) 2:2 (E) 0:4
4:0
To determine how many boxes in the Punnett square represent offspring with a gray body or a black body, consider whether each phenotype is the dominant or recessive allele's version of the body color trait. The question tells you that the B allele, which is for a gray body, is dominant over the b allele, which is for a black body. A gray body is the dominant allele's version of the body color trait. A fruit fly with the dominant version of the body color trait must have at least one dominant allele for the body color gene. So, offspring with a gray body must have the genotype BB or Bb. All 4 boxes in the Punnett square have the genotype BB or Bb. A black body is the recessive allele's version of the body color trait. A fruit fly with the recessive version of the body color trait must have only recessive alleles for the body color gene. So, offspring with a black body must have the genotype bb. There are 0 boxes in the Punnett square with the genotype bb. So, the expected ratio of offspring with a gray body to offspring with a black body is 4:0. This means that, based on the Punnett square, this cross will always produce offspring with a gray body. This cross is expected to never produce offspring with a black body.
