S alleles
S alleles (self-sterility genes) Genes that prevent self-fertilization by controlling the growth of the pollen tube, thus causing male sterility and preventing inbreeding depression in monoecious plants. Gametophytic tissue containing the same sterility allele as the sporophyte is discriminated against.
