The all-female Amazon molly (Poecilia formosa) is the result of a hybridization of the Atlantic molly (P. mexicana) and the sailfin molly (P. latipinna) approximately 120,000 years ago. As a gynogenetic species, P. formosa needs to copulate with heterospecific males including males from one of its bisexual ancestral species. However, the sperm only triggers embryogenesis of the diploid eggs. The genetic information of the sperm donor typically will not contribute to the next generation of P… Expand
The gonadal transcriptome of the unisexual Amazon molly Poecilia formosa in comparison to its sexual ancestors, Poecilia mexicana and Poecilia latipinna
TLDR
The hypothesis of general down-regulation of meiosis-related genes in the apomictic Amazon molly is supported and the obtained dataset and identified gene catalog will serve as a resource for future research on the molecular mechanisms behind the reproductive mode of this unisexual species. Expand
Nonadditive and Asymmetric Allelic Expression of Growth Hormone in Hybrid Tilapia
TLDR
The results of this study first illustrated the concept of GH expression superiority and its formation mechanism in hybrid fish with growth vigor by tracing the molecular outcomes of growth hormone (GH) expression and allele-specific expression (ASE) in hybrids. Expand

TLDR
Overall gene expression of IGF-1 and allele-specific expression in hybrid tilapia is provided for the first time, indicating a nonadditive expression pattern in the hybrid. Expand

Sequence Evolution and Expression of the Androgen Receptor and Other Pathway-Related Genes in a Unisexual Fish, the Amazon Molly, Poecilia formosa, and Its Bisexual Ancestors
TLDR
The sequence evolution and gene expression of the duplicated genes coding for androgen receptors (ars) and other pathway-related genes, i.e., the estrogen receptors and cytochrome P450, family19, subfamily A, aromatase genes (cyp19as), in the Amazon molly are studied in comparison to its bisexual ancestors.

Hybridization, Unisexuality, and Polyploidy in the Teleost Poeciliopsis (Poeciliidae) and Other Vertebrates
TLDR
The discovery of this five-fish hybrid complex from the Rio Fuerte of northwestern Mexico suggests that hybridization, unisexuality, polyploidy, hybridogenesis, gynogenesis, and parthenogenesis are related, which makes it possible to explain how large changes in DNA levels took place during the evolution of vertebrates.

POECILIA MEXICANA IS THE RECENT FEMALE PARENT OF THE UNISEXUAL FISH P. FORMOSA
Poecilia formosa, a small live-bearing fish native to northeastern Mexico, was the first recognized vertebrate with unisexual reproduction (Hubbs and Hubbs, 1932). This all-female "species" producesExpand
Monophyletic origin of multiple clonal lineages in an asexual fish (Poecilia formosa)
TLDR
The molecular phylogenetic evidence and the failure to resynthesize the gynogenetic P. formosa together with the old age of the species indicate that some unisexual vertebrates might be rare not because they suffer the long‐term consequences of clonal reproduction but because they are only very rarely formed as a result of complex genetic preconditions necessary to produce viable and fertile clonal genomes and phenotypes.

TLDR
Results of cross-amplification of 63 microsatel-lite loci, originally developed for Xiphophorus, tested in the Amazon molly and its two parental species P. mexicana and P. latipinna are reported, finding eight microsatellite loci were found to be poly-morphic. Expand
EVOLUTIONARY ORIGIN OF A PARTHENOFORM, THE AMAZON MOLLY POECILIA FORMOSA, ON THE BASIS OF A MOLECULAR GENEALOGY
TLDR
DNA sequence analyses of transcribed portions of the genome (tyrosine kinase proto‐oncogenes) demonstrated the Amazon molly Poecilia formosa hybrid state unequivocally and dates the hybridization event further back than would have been predicted on the basis of “Muller's ratchet” for an ecologically successful species.

Male mating behaviour of a molly, Poecilia latipunctata: a third host for the sperm-dependent Amazon molly, Poecilia formosa
TLDR
Using behavioural tests, it is demonstrated that P. latipunctata males actually copulate with Amazon mollies, despite a pronounced preference for conspecific females, indicating that the Amazon molly effectively exploits all available host species for its gynogenetic mode of reproduction. Expand
