Adaptive introgression of a female-competitive trait Posted on January 21, 2019January 21, 2019 by Joana Meier In a study led by Sara Lipshutz, we investigated a hybrid zone of Jacana species in Panama. We found adaptive introgression of a female-competitive trait in these sex-role reverse species. Congratulations to Sara for this great piece of work!
