Meiotic drive adaptive testes enlargement during early development in the stalk-eyed flyS. L. Bradshaw, L. Meade, J. Tarlton-Weatherall and A. Pomiankowski, Biology Letters, 18:20220352. 2022.
The sex ratio (SR) X-linked meiotic drive system in stalk-eyed flies destroys Y-bearing sperm. Unlike other SR systems, drive males do not suffer fertility loss. They have greatly enlarged testes which compensate for gamete killing. We predicted that enlarged testes arise from ... |

Meiotic drive does not cause condition-dependent reduction of the sexual ornament in stalk-eyed fliesS. R. Finnegan, M. Mondani, K. Fowler and A. Pomiankowski, Journal of Evolutionary Biology, 11. 2021.
Meiotic drive systems are associated with low-frequency chromosomal inversions. These are expected to accumulate deleterious mutations due to reduced recombination and low effective population size. We test this prediction using the 'sex-ratio' (SR) meiotic drive system of the ... |

Does meiotic drive alter male mate preference?S. R. Finnegan, L. Nitsche, M. Mondani, M. F. Camus, K. Fowler and A. Pomiankowski, Behavioral Ecology, 13:194-201. 2019.
Male mate preferences have been demonstrated across a range of species, including the Malaysian stalk-eyed fly, Teleopsis dalmanni. This species is subject to sex-ratio (SR), an X-linked male meiotic driver, which causes the dysfunction of Y-sperm and the production of all-female ... |
