Some geckos can asexually reproduce! And sometimes the babies are in fact, better off for it! For many species, asexual reproduction can cause birth defects and worse genetics. However, for some geckos, such as Heteronotia binoei, who are only female, asexual reproduction actually often leads to stronger babies!
Us cool little ladies bury eggs under rocks, logs, and sand. When the eggs hatch, they will be genetic photocopies of their mothers! And when raced against geckos of the same species who were produced due to sexual reproduction, scientists found these asexual daughters would be much faster and stronger!
Here is an excerpt from a paper on this specific type of gecko:
“We found that the parthenogenetic forms were much better athletes than the sexual forms, clearly outpacing them on the treadmill,” said Kearney. “This was a bit of a surprise because a similar study of another kind of parthenogenetic lizard from the deserts of the United States showed the opposite pattern."
