Extreme female-biased sex ratios
Syntrichia caninervis has one of the most extreme female-biased sex ratio of any plant, with as many as 17 females for every one male in some populations. But so far, most recorded sex ratio are based on presence of gametangia, which are rare in this species. For this project we are using a newly developed genetic sex-determing RFLP protocol and revisiting the very samples used in a 2000 study by Bowker et al. on expressed or phenotypic sex ratio in S. caninervis to see how the genetic sex ratio compares. This project is in collaboration with Dr. Kirsten Fisher’s lab at California State University, Los Angeles, and with UC Berkeley undergraduate research apprentice Jordan Jomsky.
