Document Summary
Human marriage customs yield 2 cultural trends: patrilocality: females move to the location of their male spouse, matrilocality: males move to the locations of their female spouse. Approach: compare genetic diversity on mtdna and y chromosome for matrilocal and patrilocal ethnic group in the same region. We can use genetic markers to understand fitness components (mating and paternity) and illuminate the evolutionary process in long-lived organisms. We can combine our knowledge of how the genome is transmitted with our knowledge of behaviour to understand genetic differences in migratory wolves. Human social behaviour will affect patterns of genetic differentiation and diversity among and within populations. Reciprocal evolutionary responses in a pair of species, caused by selection imposed by each other. Reciprocal evolutionary response in the two sexes, caused by selection imposed by each other. Reciprocal evolutionary responses in humans and their agricultural species, caused by selection imposed by each other.
