Those are questions we are thinking forward !

‘Do the recombination changes facilitate the process of divergence between the two ecotypes?’ ‘Are the changes transient, side effect of selection for or against particular combinations of genetic variants?’ Or ‘do they reflect direct modifications of the recombination rates?’

We inferred recombination histories from genetic linkage in population data and combined these results with simulations to develop a new metric (PRDI) to quantify the amount of recombination rate evolution. We found a positive PRDI in our system, the answer is yes - recombination histories differ.

In this paper, we study recombination in the context of an early stage of speciation in cichlid fishes and ask the question: ‘do recombination histories differ between closely related population?

I’m very proud and happy to share the first paper of my PhD with @millanek.bsky.social that is now published in the latest issue of the journal Evolution @journal-evo.bsky.social.

Do you want to make genetic maps from sperm/pollen/gametes? Now there is an easy way, based on Hi-C sequencing.

Thanks to Richard Durbin and Ed Green for the idea and a group of co-authors including @mariontalbi.bsky.social and @danielbolnick.bsky.social for contributions.
