Compare and contrast selective breeding and natural selection

Natural selection- happens naturally, existed since the beginning of breeding, procreate natural traits ( not specially made traits), those of natural selection live longer, is still a way of breeding like selective, those with the strongest traits still survive longer like selective breeding

Selective breeding- happens by the matching of mate's by man, usually to create a desired trait, doesn't happen naturally, may not live as long , is a type of reproduction process still like natural selection..

Ithink option a is correct because you cannot donate a different blood group than yours because it won't match.option a says betsy can donate to mark. they have the same blood group so donation can happen.
