jenniferrpovey:

50 species of lizard and one species of snake reproduce through parthenogenesis (that’s the fancy word for producing offspring as a female without having sex).

Except.

Whiptails are stimulation ovulators. That is to say, they can’t ovulate without having sex.

So not only do they are give birth through immaculate conception, they’re ALL LESBIANS.

There are two kinds of parthenogenesis seen in reptiles. That used by whiptails and the other all female species is true cloning - the egg contains the female’s full genetic material).

Other species including komodo dragons use another form of parthenogenesis where they actually fertilize themselves, with a haploid polar body used instead of a sperm. Because of the way reptile sex chromosomes work, this form of parthenogenesis can produce males as well as females - however, the females produced have weird sex chromosomes and can only lay other females. It’s used as a backup reproductive strategy if they can’t find a mate. This works because in reptiles, unlike mammals, its the males that have two sex chromosomes the same (ZZ) and the females different (ZW). Females produced by parthenogenesis are WW - and that’s what happened to the whiptails. They lost the Z chromosome and now are all WWs.

IOW?

Reptiles are fascinating.

YOOOOOOOOOOOoooooooooooooooOOOOOOOOOOOOOoooooooooooooooooooOOOOOOOOOOOO

So that means that bit I talked about on skype about lesbian dragons being able to reproduce in LotS has a basis!

What is your attitude to human cloning?

slightly negative but at some point it can be useful. yknow how we sometimes wish there were multiple of us to do multiple tasks? those are one of the cases but what if the clones will suddenly develop a mind of its own n refuse to be disintegrated? thats elementary when it comes to cartoon cliches. i think.we can just clone famoua dead people instead, that would be pretty awesome.
