I think it is misleading to say that "the sex of the animal´s offspring is decided by the male". It is decided by "the content of the male gamete forming the zygote", which, however may be chosen entirely by chance. One could even imagine a mechanism in which it is specifically controlled by the female, for that matter.

How does it work?

As I understand it, in the XY system the Y contains both the sex-determination allele and a bunch of stuff only useful to males. In the case of XX, one turns off the other to prevent double expression.

So how does this transition to an X / XX system? How do males get by without the aforementioned useful stuff? How do males know they're male when the sex-determination is absent? Since one X would turn the other off, how do females know they have a second X?

Is the transition from XY to X0 universally possible, or are there limits set by anatomy, physiology, Y or X chromosome structure, or other factors? — Preceding unsigned comment added by 82.139.81.0 (talk) 23:40, 27 November 2012 (UTC)[reply]

Deletion

I get the feeling that no one is watching this article. This in turn means that errors won't get corrected, except through chance visits, like mine.

Apparently Wikipedia doesn't have the capacity to take care of this article sufficiently. And since misinformation is worse than no information, I think that means this article should be deleted.
