The recombination landscape of introgression in yeast

Schwarzkopf, E. J., Brandt, N., & Heil, C. S. (2024, January 5).

By: E. Schwarzkopf  n, N. Brandt n & C. Heil n 

TL;DR: The results indicate that recent hybridization can significantly influence the recombination landscape, and suggest that the reduction in allele shuffling contributes to the initial purging of introgressed ancestry in the generations following a hybridization event. (via Semantic Scholar)
