In humans, having brown hair is dominant to having blond hair. How is it possible that two brown-haired parents have a blond-haired child? Both parents have brown hair but their genotype is homozygous. Both parents have brown hair but their genotype is heterozygous. One parent has an allele for blond hair that was passed on to the child. The brown hair alleles changed to blond hair when inherited by the child.

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.

what? are the statements?

i think the answer is a.keratin is the pigment responsible for skin color.
