Three chromosomal factors called Spore killer (Sk) have been found in wild populations of Neurospora sitophila and N. intermedia. Sk resembles other examples of meiotic drive such as Segregation Distorter in Drosophila, Pollen killer in wheat, and Gamete eliminator in tomato. In crosses heterozygous for Sk, each ascus contains four viable black ascospores and four inviable, undersize, clear ascospores, with second-division segregations infrequent. The survivors contain the killer allele Sk(K… CONTINUE READING
