Guys we are losing our Y .....

It sounds like I'll be able to shag myself which must be a good thing surely on account of all the money and trouble I'll save.

Nah, almost all of the material found in the Y chromosome is also found in the X chromosome. All the Y chromosome needs to do is trigger some process that leads to your becomming a male, or possibly not trigger some process (which would be triggered by two X chromosomes) that would make you a female. The "genetic blueprint" for both male and female is found outside the Y chromosome.

Mating wouldn't be affected:

. . . . (XX) (XY)

(XX) (XY) (XX) (XY)


. . . . (XX) (X -)

(XX) (X -) (XX) (X -)

This is a myth which has been debunked. I suggest browsing snopes, as they might have the scientific counter-proof.

Anyway, that would be parthenogenesis, not cloning.

I have my objections to this....



But all those counterproofs talk about is "for last 6 million years the Y chromosome has not disintegrated so it has assumed to reach its minimum size and has lost power of further disintegration " But what about before 6 million years back where it HAD disintegrated!

Also there no reason to NOT to assume that Y will not disappear. It had happened with oldest living fossils most of them reptiles and amphibians like frogs, salamanders and some lizards species who had lost Y.

So that ONE DAY i wrote about will not be in near future but certainly in distant future though .....



Agree there! I misunderstood.



Vaguely they are same. Parthenogenesis is seen as a possible legal way to clone primates including humans.

Have they proven that it was disintegrating 6 million years ago?

Dunno


Dunno but they say it that way....
