Circles represent obstruc- tion of mating; broken circles by discrimination against inbreeding, unbroken by selection against remote crossing. Horizontal hatching represents exclusion from remote crossing, diagonal from crossing with the like sex. hi Plants incompatibility of the too-like and the too-unlike arc the agents; in Animals mating discrimination against the too-like and the too-unlike; in Europeans taboos and laws against incest and mating preferences; in Hindus the example illustrated represents the working of high caste rules in North India: the prohibition of inbreeding extends to sapindas, the 6th cousin on the male side and 4th on the female; outbreeding is also more restricted for females than for males by the hypergamy rules which prevent women but not men marrying beneath them so that the possible mates for a female may be reduced to a small fraction of unity. 357.
