Cryptic #sexChromosome was found after removing a master sex-determining #chromosome. This result suggests that #polygenic #sexDetermination system may be more prevalent than previously thought.

I am so privileged to attend Tree of Sex ver. 2.0 workshop at Wellcome Sanger institute. I am an out-of-the-field researcher in the group, but they are so nice and fun! (Still that was one of the scariest presentations I have ever done..)

#Wolbachia bacteria live inside #insect cells and transmit from mom to offspring. Some have adapted to kill male insects. This paper from #PNASNexus uses #CellCulture to determine that Wolbachia kill males by impacting the expression of #SexDetermination #genes in #moths.
