Document Summary

Birds, butterflies and moths have z and w chromosomes. Low recombination is low crossing over in gametes. High recombination is high crossing over in gametes and this has a big effect on the chromsomes. If theres a region of high recombination, the genes can be inherited somewhat independely because the genes can dissociate from its neighbor on a chromosome. Females stay in their netal groups but once males become adolescents they are kicked out of the groups. 2nd hypothesis is that inbreed offspring could be just as good as outbred offspring. If they avoid inbreeding, mles will mate with females they are not related to. In family groups, males direct their attention towards non-relatives. Even in the 2nd graph male elephants have evolved to direct their attention away from their relatives. Elephants thus can avoid mating with their relatives. They got samples from hair and they tried to cluster the genetic data to see which groups are more closely related.
