Frequency-dependent selection models are what Marjorie Asmussen did, and I worked in her lab for a while, so the term is familiar to me–just like cytonuclear disequilibria–but I certainly am ignorant on these topics.
In this study, Dr. Leu and his colleagues attempted to determine whether cytonuclear incompatibility is a common cause of reproductive isolation in yeasts.
"Our results suggest that cytonuclear incompatibility can be achieved by multiple molecular mechanisms and it potentially represents a general mechanism of reproductive isolation in yeast species," said
They revealed that most of the hybrid spores were respiration-deficient, indicating cytonuclear incompatibility.
