I read this paper:
Bachtrog D, Mank JE, Peichel CL, Kirkpatrick M, Otto SP, Ashman TL, Hahn MW, Kitano J, Mayrose I, Ming R, Perrin N, Ross L, Valenzuela N, Vamosi JC (2014) Sex determination: why so many ways of doing it? PLoS Biol. 12(7):e1001899.
And now I give you a quick summary of a couple of figures that I know you’ll find useful if you’re teaching genetics.
Becca Stareyes says
So, if species like zebrafish have many genes determining if they are sperm or egg producers, and their developing one way or the other comes down on how many, what happens if they end up with an even number (as diploid individuals can, given we usually have two copies of genes outside of sex chromosomes)?
Mark Dowd says
So you’re saying that sex is all fucked up?
These are the jokes, people.
Or arguing with transphobes, who often bray about science while thoroughly lacking an understanding of same.
Raucous Indignation says
I love chromosomes! They look so fluffy!
