Rapid comeback of males: evolution of male-killer suppression in a green lacewing population

Hayashi, MN, M.; Kageyama, D.,  Proceedings of the Royal Society B-Biological Sciences,  285:6. 2018.
Evolutionary theory predicts that the spread of cytoplasmic sex ratio distorters leads to the evolution of host nuclear suppressors, although there are extremely few empirical observations of this phenomenon. Here, we demonstrate that a nuclear suppressor of a cytoplasmic male ...

Centromere strength provides the cell biological basis for meiotic drive and karyotype evolution in mice

Chmatal, L., S. I. Gabriel, G. P. Mitsainas, J. Martinez-Vargas, J. Ventura, J. B. Searle, R. M. Schultz and M. A. Lampson,  Current Biology,  24:2295-2300. 2014.
Mammalian karyotypes (number and structure of chromosomes) can vary dramatically over short evolutionary time frames [1-3]. There are examples of massive karyotype conversion, from mostly telocentric (centromere terminal) to mostly metacentric (centromere internal), in 102-10 s ...
