Fish mollies sex

For all intents and purposes, the Amazon molly should be on a crash course to extinction. Over time, the all-female species of the Amazon molly, a freshwater fish native to the border region of Texas and Mexico, has figured out how to clone itself without any male DNA. Scientists have long theorized that this form of sexual reproduction—called gynogenesis—would usher in extinction for the Amazon molly. Most species that employ or had employed asexual reproduction are marked by a lack of genetic variation.

Amazon molly - Wikipedia

The Amazon molly Poecilia formosa is a freshwater fish native to warm, fresh waters between Tuxpan River in northeastern Mexico and the Rio Grande and the Nueces River in the extreme southern parts of the U. The common name acknowledges this trait as a reference to the Amazon warriors , a female-run society in Greek mythology. Reproduction is through gynogenesis. This means although females must mate with a male, genetic material from the male is not incorporated into the already diploid egg cells the mother is carrying except in extraordinary circumstances , resulting in clones of the mother being produced en masse.

Topic : I have a molly fish aquarium setup and was wondering what the differences in male or female tail types were? Is there a way to sex mollies and tell a difference between female or male? I want to start breeding my fish and selling them for profit.
