Genetic explanation for the appearance, Biology

Assignment Help:

You work with flies and you have identified a single gene that can cause flies to either have two heads or one head (depending on the genotype of this gene), and that is all you know for now. Say you take a fly with two heads and you cross it to a fly that has one head. This cross results in progeny of the following kinds: 198 with two heads and 234 with one head. a) come up with a genetic explanation for the appearance and genotype of the parents and offspring of this cross. b) show that your explanation passes a chi square test. c) Is there anything ambiguous about these results and your model (are there other explanations)? If som what is another explanation and what additional experiments (crosses perhaps) would you do to resolve this ambiguity. If not just write no
