- Data set A summarizes F2 numbers from an F1 cross arising from two, true-breeding Drosophila strains (P generation), which differ with respect to two mutant traits. The traits of legs shows an autosomal incomplete dominance pattern and the traits for wings shows an X-linked regular dominance pattern. a) Produce a genetic hypothesis about the mode of inheritance of each of the alleles from your data set. You must come up with a hypothesis that both makes sense and will not be rejected, in other words, you need a hypothesis that will corroborate the experimental observations. b) Explain/describe how the data set seems to support your genetic hypothesis for each trait. For example, explain why you think a trait is recessive vs dominant or X-linked vs autosomal. To do this, you could comment on the observed ratios and/or differences or similarities in male and female numbers and explain how these provide support for your hypotheses. c) Assign genetic symbols to the four alleles involved.…arrow_forwardWhich of the following statements is FALSE?
