Document Summary
Many organisms live in groups: advantages and disadvantages of living in a group. Altruistic (self sacrificing behaviour: meaning of dominance hierarchy, kin selection, altruism, reciprocal altruism, eusocial, haplodiploidy, calculate degree of relatedness between two individuals, given the type of relationship (parent-offspring, Selection is fundamentally competitive cousins, etc: identify why haplodiploidy can favour high levels of cooperation in social insects. Diff in relative finesses b/w diff genotypes. Individuals are constantly competing w/ other individuals of the same species in order to get a larger fraction of their alleles to be represented in the next generation. Constantly competing with same species, to get larger fraction of their alleles. Competition b/w females w/in a species females parasitize the reproductive investment of other. Form of males competing for other males for access of females. Other females may sneak in and dump their own eggs in that nest = group parasitism.
