Battle of the sexes

In the battle of the sexes, one species whipped the male species to extinction and emerged a winner. It is the whiptail lizard. There is no male whiptail lizard found in the world anymore. Then how does this species still sustain? The females don't need the males any longer to reproduce. The females pair up(a lesbianism found in nature) and copulate to produce unfertilized eggs which result in the development of juveniles exact clones of the mother.

In humans, what u people thought of the Y chromosome? It is a smaller chromosome with only 36 genes while the X chromosome contains 1500 genes. And it is found that this number of genes in X chromosome to be decreasing which may result in wiping out of Y chromosome in another 125,000 years. So in a distant future, humans too won't need male to reproduce. Fascinating, isn't it?

Typo up there. The number of genes in Y chromosome is found to be decreasing and not the X chromosome.
