If Jennifer is normal (and is not a carrier) but her husband, James, is colorblind, what are the chances of their daughter, Jean, being colorblind?

0

Explanation:

This question involves a single gene coding for sight in humans. The allele for normal vision (C) is dominant over the allele for color blindness (c).

Based on the question, If Jennifer is normal (and is not a carrier) i.e. she has a genotype CC, and her husband, James, is colorblind with genotype cc. Each parent will produce C and c gametes respectively. Using these gametes in a punnet square (see attached image), all of the offsprings will have the genotype Cc, which is phenotypically normal visioned.

Therefore, according to this question, the chance of their daughter being color blind is 0.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
