The trait called "bobbed hairs” in the fruit fly (Drosophila) is recessive and is located on the X chromosome only. Assume all flies are true-breeding. We would like to figure out if this gene is carried on an autosome or a sex-chromosome. a Carry out a cross (on paper) to the F2 generation between a bobbed male and a true- breeding, wild type (normal) female. Show all genotypes, phenotypes, and their percentages. At what point in the cross (at which generation) would the results show you whether this trait is a sex-linked or a normal (autosomal) trait? (Hint: To answer this, you'll need to carry out this problem, to the F generation, as if it is normal (autosomal) AND as if it were sex-linked. Then you should compare your F. and F. results. So the question is asking, at which generation, F or F, do the results come out differently if autosomal or if sex-linked?) b. Carry out to the F2 generation the reciprocal cross to the above. (Start with a bobbed female and a normal male in the P1.) Show all genotypes, phenotypes, and expected fractions or percents. At what point in the cross would the results show you whether this trait is a sex-linked or a normal (autosomal) trait?​
