Document Summary
Psych 3f03 lecture 28 - reciprocity 2. Have a weird genetic structure haplo-diploid, some bees have 2 some have 1 set of chromosome: haplo-diploid sex determination in bees, we (humans) are diploid (have pairs of chromosomes) Queen bee is diploid, she breeds male drones (haploids, only dna from mother, 1 set of. Dna: mate with mom, queen mates with genetically related father. Share more than 50% (usually around 75%) dna with siblings. This is the binding glue to their eusocial behaviour. If an individual can successfully do something difficult or dangerous and there is an audience to appreciate this display, then this form of showing-off can be an honest (unfakeable) signal of quality. Hunting large game is a candidate case of an honest signal of one"s phenotypic quality (expertise, strength, vigour, etc. ) In several hunting societies, men"s contribution to total calories is not reliable and often less than women"s contributions from foraging.
