The gonadal transcriptome of the unisexual Amazon molly Poecilia formosa in comparison to its sexual ancestors, Poecilia mexicana and Poecilia latipinna [PDF]
BMC Genomics, 2018 Background The unisexual Amazon molly (Poecilia formosa) originated from a hybridization between two sexual species, the sailfin molly (Poecilia latipinna) and the Atlantic molly (Poecilia mexicana).

Sperm specificity and potential paternal effects in gynogenesis in the Amazon Molly (Poecilia formosa) [PDF]
PeerJ, 2023 The Amazon Molly (Poecilia formosa) reproduces by gynogenesis, a relatively rare form of asexual reproduction where sperm is required to trigger embryogenesis, but male genes are not incorporated into the genome of the embryo.

The complete mitochondrial genome of Poecilia formosa (Poecilia, Cyprinodontidae) and phylogenetic studies of cyprinodontiformes [PDF]
Mitochondrial DNA. Part B. Resources, 2019 We report the complete mitochondrial genome sequence of Poecilia formosa. The genome is found to be 16636 bp in length and has a base composition of A (29.59%), G (14.61%), C (28.26%), and T (27.54%).

Enrichment effects on growth, health, and reproduction in a single clone of the asexual Amazon molly, Poecilia formosa [PDF]
PeerJThis study examines the impact of two types of environmental enrichment on the growth of the Amazon molly (Poecilia formosa), a clonal fish species. We investigated the effects of two welfare-related enrichment factors: physical enrichment (presence of a

Kin Recognition in a Clonal Fish, Poecilia formosa. [PDF]
PLoS ONE, 2016 Relatedness strongly influences social behaviors in a wide variety of species. For most species, the highest typical degree of relatedness is between full siblings with 50% shared genes.

Achiasmatic meiosis in the unisexual Amazon molly, Poecilia formosa. [PDF]
Chromosome Res, 2022 AbstractUnisexual reproduction, which generates clonal offspring, is an alternative strategy to sexual breeding and occurs even in vertebrates. A wide range of non-sexual reproductive modes have been described, and one of the least understood questions is how such pathways emerged and how they mechanistically proceed. The Amazon molly,Poecilia formosa,

Allele-specific expression at the androgen receptor alpha gene in a hybrid unisexual fish, the Amazon molly (Poecilia formosa). [PDF]
PLoS ONE, 2017 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.

Female sperm limitation in natural populations of a sexual/asexual mating complex (Poecilia latipinna, Poecilia formosa). [PDF]
Biol Lett, 2008 In sperm-dependent sexual/asexual mating systems, male mate choice is critical for understanding the mechanisms behind apparent stability observed in natural populations. The gynogenetic Amazon molly ( Poecilia formosa ) requires sperm from sexual males (e.g.

Comparative analysis of the gonadal transcriptomes of the all-female species Poecilia formosa and its maternal ancestor Poecilia mexicana. [PDF]
BMC Res Notes, 2014 The Amazon molly, Poecilia formosa (Teleostei: Poeciliinae) is an unisexual, all-female species. It evolved through the hybridisation of two closely related sexual species and exhibits clonal reproduction by sperm dependent parthenogenesis (or gynogenesis) where the sperm of a parental species is only used to activate embryogenesis of the apomictic ...
