Amazon Molly Asexual Reproduction Mechanism Discovered

Researchers at the University of Missouri, led by Wes Warren and Edward Ricemeyer, have identified the genetic mechanism, gene conversion, that allows the Amazon molly, an all-female fish species, to thrive despite reproducing asexually. This finding challenges the long-standing scientific belief that asexual reproduction is an evolutionary dead end due to genetic disadvantages. The Amazon molly, which emerged over 100,000 years ago, maintains genetic health by using gene conversion to repair and preserve DNA, mimicking the benefits of sexual reproduction. The study, published in Nature (journal), suggests that other asexual animals might use similar processes and has implications for genome evolution research and its practical applications.
