Autogamy is the closest form of inbreeding. Autogamy leads to homozygosity. Such species develop homozygous balance and do not exhibit significant inbreeding depression.agritech.tnau.ac.in/crop_improvement/crop_imprv_…Self pollination, also known as autogamy, is the process by which a flower’s own pollen fertilizes its own ovules. In simpler terms, it is when a flower can reproduce without the need for pollen transfer between different flowers.pollenpaths.com/plants-self-pollination/As described by the International Union of Botanical Sciences, autogamy refers to a sort of self-pollination that is mostly found in flowering plants and in which the pollen grains of an anther of a flower are deposited on the stigma of a different plant.
