another molly fact

[wrs]

mollies can cross breed with any fish in the Poecilia family with fish such as GUPPIES and Lima live bearers. They fry dont survive though.

Not only do the fry survive, they are also blessed with hybrid vigor, making them stronger and larger than either parent. This is called an F1 hybrid.

Not all of the fry are sterile either and can go on to breed with other hybrids or other pure poecilia species.

Here's a picture of a molly/guppy cross from the book Guppies by Axelrod and Whitern, published by TFH (although it just looks like a molly to me!)

Mollies are also capable of reproducing by pseudogamy which is a form of stimulated parthenogenis.
This means that when mated by a male of any species with the right 'equipment' the female's eggs are stimulated into growing without the male's sperm fusing with the eggs.
This results in offspring that are in fact clones of the mother and carry none of the male's genes at all.

Parthenogenis is also found in several other species of fish, many insects, frogs, reptiles....and the Dinosaurs from Jurrasic park!

i know that last part, all females. i posted that in another post, lol. but i read that the fry really dont survive because of hard time swimming etc.
