Let me tell you 'bout the birds and the bees and the octopuses:

#Octopuses have some of the oldest known #sexChromosomes
New research at the UO shows they’ve been using one that’s been around for 480 million years

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.

How and why temperatures determine the sex of turtles? https://phys.org/news/2023-06-temperatures-sex-turtles.html

Higher temperatures directly increase germ cell number, promoting feminization of #RedEaredSlider turtles https://www.cell.com/current-biology/fulltext/S0960-9822(23)00758-3

"Warmer temperatures make more #turtle eggs become female hatchlings... those females also have a higher capacity for egg production, even before their sex is set. This may explain why many #animals besides #turtles have temperature-dependent #SexDetermination"
