Meiotic drive caused by the Sk-2 spore-killer gene in Neurospora. In Neurospora, the meiotic progeny obtained after a sexual cross form bunches of eight-spored asci (spore sacs). Asci are eight-spored due to a postmeiotic mitotic division that makes eight haploid spores of the four meiotic products. When a Sk2k killer strain is crossed with a sensitive Sk-2s strain, all spores that do not contain the Sk2k killer gene fail to mature and die, yielding asci with four unviable white Sk-2s spores and four normal black Sk-2k spores. Homozygous crosses between killer strains or sensitive strains yield normal asci.
