Sox9 gene regulation and the loss of the XY/XX sex-determining mechanism in the mole vole Ellobius lutescens

@Bohemian696 Mutace vždycky neznamenají, že je něco špatně, viz hlodavec druhu Slepušky ponské nemající chromozom Y. https://t.co/F26ZyFNgGH

@Iluminator_cz @Bohemian696 U hlodavce druhu Slepušky pontské (Ellobius lutescens) chromozom Y vymizel. https://t.co/F26ZyFNgGH

@downs1nthehouse @AiG For example, in humans, the SRY and SOX9 genes are responsible for determining sex, while in fruit flies, the genes dsx and fru are responsible. Mutations in any of these genes can lead to a change in an organism's sex. As seen here:

If I was going to offer "my favourite fact this week" for @nosuchthing As a Fish, I would say this: There exists in the world an animal called a "mole vole", and most species of mole voles don't have Y chromosomes (but do have males) https://t.co/0X2Y2PW
