There's a family of lesbian lizards? WHAT THE FUCK, /an/. You're supposed to keep me informed of this stuff.

Parthenogenesis is superior to sexual reproduction.

Only if you're unicellular or want to go extinct soon.

Ya rly.

Parthenogenesis over several generations is essentially reproduction through cloning. Any multicellular animal that gives up sexual reproduction completely is doomed to extinction. This is probably because the drastic drop in genetic variation in the offspring makes them unable to diversify and cope with rapid changes in the environment.

No wai.

Thats why multicellular organisms like the Komondo Dragon I posted can reproduce with both methods amirite?

It allows to get them over rough spots but long term they need to damn lucky to survive.

In scotland there is a herd of highland cattle that has been interbreed for some 1000 years or so and is practically a herd of clones.

Their luck was was humans moderating outside influences.

For that matter many during the dark ages in europe and probably until recently in china there was very little interbreeding done in rural communities, with estimates putting roughly one outsider in a breeding group (=village) in a century.

I think you're misunderstanding the nature of parthenogenesis; it's quite different from cloning. Here, let Auntie Wikipedia explain it to you:

"Parthenogenesis is distinct from artificial animal cloning, a process where the new organism is necessarily genetically identical to the cell donor. In cloning, the nucleus of a diploid cell from a donor organism is inserted into an enucleated egg cell and the cell is then stimulated to undergo continued mitosis, resulting in an organism that is genetically identical to the donor. Parthenogenesis is different, in that it originates from the genetic material contained within an egg cell. Egg cells may be produced via meiosis or mitosis oogenesis.[4] If by mitosis, the egg that undergoes parthenogenesis can be either haploid or diploid, leading to a number of possible outcomes in terms of the genetic fingerprint of the parthenogen (one created via parthenogenesis). Whether the parthenogen is haploid or diploid, because meiosis was involved in forming the gamete that subsequently underwent parthenogenesis, incidence of crossing over would effectively create a new genetic fingerprint; this would be of particular importance in the case of a haploid parthenogen, in which crossing over would drastically alter its single chromosome genotype. Because there are so many variables in parthenogenesis, there is little that can be said for sure unless the specific methods of the particular parthenogenetic tendencies of an organism are known."

You neglected to read what Auntie Wiki says next:
>>What is for sure, though, is that a litter of offspring resulting from parthenogenesis may contain genetically unique siblings. In organisms possessing an XY chromosome system in which parthenogenic offspring are female, parthenogenic offspring of a parthenogen would be genetically identical to that parthogen because all offsprings of parthenogenesis would be homozygous.

Or translated into common English: When an animal born out of parthenogenesis has offspring parthenogenetically, all the resulting offsprings are identical to the mother, i.e. clones.
