The rate of facultative sex governs the number of expected mating types in isogamous species

GWA Constable, H Kokko - Nature Ecology & Evolution, 2018‏ - nature.com
It is unclear why sexually reproducing isogamous species frequently contain just two self-
incompatible mating types. Deterministic theory suggests that since rare novel mating types …

Restricted distribution and limited gene flow in the model ciliate Tetrahymena thermophila

RA Zufall, KL Dimond, FP Doerder - Molecular Ecology, 2013‏ - Wiley Online Library
The biogeography of microbial eukaryotes has long been debated, but few phylogeographic

Fitness differences suppress the number of mating types in evolving isogamous species

Y Krumbeck, GWA Constable… - Royal Society Open …, 2020‏ - royalsocietypublishing.org
Sexual reproduction is not always synonymous with the existence of two morphologically

Invasion and extinction dynamics of mating types under facultative sexual reproduction

P Czuppon, GWA Constable - Genetics, 2019‏ - academic.oup.com
In sexually reproducing isogamous species, syngamy between gametes is generally not
indiscriminate, but rather restricted to occurring between complementary self-incompatible …

Evolution of mating types in finite populations: The precarious advantage of being rare

P Czuppon, DW Rogers - Journal of Evolutionary Biology, 2019‏ - academic.oup.com
Sexually reproducing populations with self‐incompatibility bear the cost of limiting potential
mates to individuals of a different type. Rare mating types escape this cost since they are …

Mating Systems and Reproductive Strategies in Tetrahymena
