Abstract excerpt
Recombination in ancient, heteromorphic sex chromosomes is typically suppressed at the sex-determining region (SDR) and proportionally elevated in the pseudoautosomal region (PAR). However, little is known about recombination dynamics of young, homomorphic plant sex chromosomes. We examine male and female function in crosses and unrelated samples of the dioecious octoploid strawberry Fragaria chiloensis in order...
