Document Summary
Psyc 110 - lecture 4 - genes, behavior, and selective breeding. R-selection: high reproductive rate, little to no investment. R strategy- create an abundance of offspring and hope that a few will survive. K strategy- ensure survival of offspring by investing time into them. Drives the courtship and mating patterns of a species. Costs: time, energy, money, risk of survival, equality/inequality of parental investment. Necessary when conditions do not allow for a single female to raise her offspring. Permits group to live in relative harmony. Parental confusion encourages access to multiple resources, group cares for young. Genetic diversity- ability to mate with many females. Low-ranking males have ability to mate and pass on their genes. One male fathers offspring from multiple females. If mates are deterred by male competition, non-dominant female gets chance to breed with a dominant male. Able to sire many more offspring than otherwise capable of a single female. High male parental investment, low female parental investment.
