“…The studies of SD, het-s, Sk, and other examples described by Lyttle (1991a,b), Dalstra et al (2003Dalstra et al ( , 2005, and Burt and Trivers (2006) show that there are several diverse cellular mechanisms that can trigger meiotic drive. However, the Podospora [Het-s] prion, the Drosophila SD locus, and the mouse t locus are the only three meiotic drive elements that have been characterized at the molecular level (Schimenti 2000;Kusano et al 2001Kusano et al , 2003Maddelein et al 2002;Dalstra et al 2003Dalstra et al , 2005.…”

“…If the het-s expression stops during the sexual cycle, the late asci would inherit fewer prion seeds and thus killing percentages would diminish. 27 An alternative hypothesis, is that the progressive build up of the HET-S protein in the ascogonium during perithecial maturation leads to curing of the [Het-s] prion in late asci. Indeed, it is important to note that in this cross, the majority of the het-s ascospores are cured from the prion (even though the maternal parent was [Het-s]), this loss of [Het-s] indicates that het-S exerts a prion curing effect in a large fraction of the asci.…”
