Answer:
The results can be explained if the mutation for bag wings is sex-linked, dominant, and lethal in males.
Explanation:
When a trait is differently expressed in males and females, we must suspect that it's sex-linked.
If we consider the mutation for bag wings as sex-linked and dominant (B), and the wild-type allele (B+) is recessive, then the<u> expected offspring</u> resulting from the cross between a bag-winged female XᴮXᴮ⁺ (heterozygous) and a WT male Xᴮ⁺Y would be:
- 1/4 XᴮXᴮ⁺ bag-winged female
- 1/4 Xᴮ⁺Xᴮ⁺ wild-type female
- 1/4 Xᴮ⁺Y wild-type male
- <u><em>1/4 XᴮY bag winged male</em></u>
But the bag-winged male doesn't appear in the progeny, and the observed proportions of the other phenotypes are 1/3 each. This suggests that the mutation is lethal in males, and maybe in homozygosis in females as well.
The answer is events. I had the same question on one of my tests and I got it right

False, by drinking too much you can easily put someone else at risk. Whether it be from driving with them while your judgement is impaired or even simply falling onto them by slipping.
