Question

Draw all possible positions of the wing shape gene compared to the body type and antenna type on a chromosome

You have being given a new species of insect on which you will conduct a genetic experiment. In the P generation, you cross two true-breeding insects. The female has a wood stick-like body and short antenna, the male has a leaf-like body and fanned antenna. All the flies in the F1 generation have a wood stick-like body and a fanned antenna.

Associate the alleles with the appropriate letter, with “B” an “b” for body type and “A” and “a” for antenna type. The uppercases “B” and “A” indicate the dominant allele, the lowercases “b” and “a” the recessive allele.
