Locus	Cultural Requirements	Link Group	Type
Sk-3	Near the centromere. The killer allele Sk-3K suppresses crossing over in the interval r(Sk-2)-1-leu-1 (29% in controls). Recombines with his-7 (11%) but not with leu-1 (0/72) or acr-7 (0/60,000) and only 3/19,000 with acr-2. (1092; B.C. Turner, personal communication) Origin and characteristics resemble those of Sk-2, q.v. However, Sk-3K strains are sensitive to killing by Sk-2K and vice versa. The killer allele was found in N. intermedia, introgressed into N. crassa. Most wild-type strains of both species are sensitive, but resistant strains of N. intermedia have been found. Strains resistant to Sk-3K are not necessarily resistant to Sk-2K (857, 1092).		B
