You are a researcher who is interested in three genes indrosophila: The a gene, the b gene and the c gene. You think thegenes may be linked, so you decide to do a cross using atrue-breeding a+/b+/c+ fly and an a/b/c fly. The F1 generation isall a+/b+/c+. However, when the F1 generation is bred to atrue-breeding a/b/c fly, it yields the following offspringphenotypes: 596 a+/b+/c+ ; 589 a/b/c ; 183 a+/b/c ; 176 a/b+/c+ ; 0a/b+/c ; 0 a+/b/c+ ; 0 a+/b+/c ; 0 a/b/c+. Which What is a possibleinterpretation of your results?
Group of answer choices
The b and c genes demonstrate 100% (complete) linkage.
The b and c genes are recessive lethal alleles.
The a gene is a dominant lethal allele.
The a and b genes demonstrate 100% (complete) linkage.
