The rh antigen is another genetically determined antigen that may occur on the surface of human red blood cells. individuals with this antigen are said to be rh-positive and those without it are rh-negative. the allele for the production of this antigen, rh, is dominant to the rh allele for nonproduction of the antigen. the locus for the rh gene assorts independently of the locus determining abo blood types. determine whether parents with the following sets of genotypes could have a child with a, rh-negative blood. in each case, explain why or why not.

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.

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.
