Question

When flies having a gray body and normal wings were crossed with flies having a black body and vestigial wings, the F2 generation showed a phenotypic ratio of 3:1, and not 9:3:3:1.
Which of the following could be a correct explanation for this ratio?

A- Genes for body and wing size were on the same chromosome and inherited together
B- Genes for body and wing size assort independently
C- Genes for body color and wing size are inherited separately from each parent

Answer 1

I thin the correct explanation for this ratio would be : A. Genes for body and wing size were on the same chromosomes and inherited together

Since it's told that the ratio is not 9:3:3:1 , we know that the traits for wings and body type are not connected

hope this helps
