Answer:

H Flies with long wings can produce offspring with short wings.

Explanation:

For example, if we name the gene for the wings length with A, then the fruit flies with short wings have the genotype aa (recessive homozygous), while those with long wings can have either AA (dominant homozygous) or Aa (heterozygous) genotype. So, if two fruit flies with long wings and Aa genotype are crossed:

P: Aa  x  Aa

F1: AA Aa Aa aa

There is a 25% chance that offspring will have short wings.

What percent of the of the father's possible gametes are consistent with producing offspring with cri-du-chat syndrome?
CaHeK987 [17]
<span>In 80% of the cases of offspring with cri-du-chat syndrome, the father's gametes were the source of the deletion of the chromosome as opposed to the mother's egg being the cause. Therefore, cri-du-chat is largely caused by the father's genetics, not the mothers.</span>
