WASHINGTON — An all-female freshwater fish species called the Amazon molly that inhabits rivers and creeks along the Texas-Mexico border is living proof that sexual reproduction may be vastly ...

When a pair of freshwater fish species reproduce together, they create hybrids who are able to reproduce asexually. This ability should offer the hybrids an unstoppable evolutionary advantage…so why ...

The Amazon molly (Poecilia formosa) is a species of freshwater fish native to Mexico and the southwestern United States. The fish—like their namesake, the mythical Amazonian warriors—are all female.

Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, ...

When a red-bellied dace and a finescale dace (freshwater fish in the carp and minnow family) mate with each other, they produce a hybrid with a very special ability: it can reproduce asexually. This ...

Even though there are only female Amazon molly fish, they can't actually survive without males. The rest of this article is behind a paywall. Please sign in or subscribe to access the full content. It ...

Andrew Fields wasn’t looking for a miracle. The Ph.D. candidate at Stony Brook University’s School of Marine and Atmospheric Science was just doing some routine genetic sampling of his study organism, ...

Not all creatures need to breed to produce offspring. Animals like zebra sharks and killifish are redefining what scientists thought they knew about asexual reproduction. Gabe Allen is a ...

For the first time, scientists have discovered a fish capable of cloning itself. The trickster in question is a small Portuguese fish that managed to steal an egg to do the deed. This is an example of ...
