Darren Irwin (he / him) @darrenirwin.bsky.social · 09/08/2026But yes there are also lots of ideas in the literature about how meiotic drive could have influenced the early evolution of all sorts of things, including the structure of chromosomes and centromeres and the nature of meiosis and sexual reproduction itself. Fun to think about. 120 0
Darren Irwin (he / him) @darrenirwin.bsky.social · 09/08/2026Maybe. I think one of the major ideas in the literature regarding asymmetric spindles is that the two meiotic divisions are each asymmetric in terms of the overall cell--with the larger volume going toward the egg. That necessitates / creates a molecular asymmetry to the whole cell division . . . 100 0
Darren Irwin (he / him) @darrenirwin.bsky.social · 09/08/2026That is certainly possible. It is also possible that female drive can arise under essentially a one-locus model--changes in the centromeric sequence (and number of repeats) alone can give a centromere an advantage in getting into the egg. There is a lot of evidence for this in the literature. 110 0
Darren Irwin (he / him) @darrenirwin.bsky.social · 09/08/2026Female meiotic drive is usually using quite different mechanisms than male meiotic drive. The preprint (and references there) summarizes those differences: female meiotic drive is usually about attaching to spindle leading to one egg; male meiotic drive usually about killing sperm without driver. 000 0
