Document Summary
Hardy weinberg the aa, aa or aa allele can be maintained based on which combination is more beneficial. Female aggregation may drive male territory defense female defense polygyny. A male with a larger territory may attract more females resource defense polygyny. Trends in relationship between mating systems and parental care. External fertilization more likely to have male care. Internal fertilization more care by parents in which zygotes develop. Fitness: the relative ability to transfer one"s genes, or copies of them, into the next generation. Inclusive fitness = fitness which is based on either personal reproductive success (direct) or that of individual that carry copies of one"s genes (indirect) hamilton, 1964. *similar to idea of f, inbreeding coefficient, but they are calculated and used differently. If the net fitness benefit to beneficiary, time the coefficient of relation is greater than the costs to donor, then cooperation can occur.
