The original lyre and hifin genes are, as with all abnormal genes not normally found in the wild (natural selection. would a hifin or lyre swordtail have better survival chances in the wild? NOT from predators but maybe in sexual selection), nothing more than mutations. In a domesticated environment, people breed a lot, so the rate of such mutations showin up are greater. Then they preform selective breeding for whatever traits they want, such as the lyre and hifin.
To be noted: almost all swordtail variations have already been discovered and bred for.

This article says that the male lyretail cannot mate naturally, but that a female that was conceived by artifically insemination from both lyretail parents will produce lyretail offspring when crossed with a normal tail male.
Interesting genetics.

Artificial insemination is common when developing different strains that would not otherwise be able to reproduce. Nothing to do with boredom.
If a randomly produced male lyretail occurs, it cannot breed because its reproductive organ is too large to be compatable with a female, so it would be a rare thing to even have a lyretail. By using artificial insemination, the commercial breeders are increasing the 'rare' thing to make it more common, to be able to sell more.
I do not like artifically created strains due to the relative unhealthiness of some strains. I've only bought oddball fish from those that either collect from the wild or that have been bred in a hobbyists' tank, rather than a common fish bred commercially. To think what has happened to the poor neon tetra...

Didn't mean to offend. Just wanted to point out how this fish came about. It is not uncommon in the commercial breeding of fish to do this sort of thing. I was not suggesting that a hobbyist do this (in fact, I am against it ethicly).
If you get a male lyretail swordfish, this is how it was created. He cannot breed. If you get a female lyretail, she ws also created this way, but she can be bred to a normal tail and produce lyretail offspring.

same thing goes for dog breeds, most of the pure breds are a hundreds of years of selective breeding giving certain breeds wierd issues like dalmations go crazy in old age or rotties all have bad hips and like my poor golden lab/ golden retriever mix (she came from pure breed parents) got bone cancer which the vet told us is genetic for both lab and retriever of the golden variety.
not to mention all the genetic play with food, you guys like your fresh firm tomatoes? well to get them to make it from the field to the store they have been crossed with a gene from a jellyfish to prevent bruising. but damn are they tasty and really juicy hahahaha
