Triploid Hybrids between the All-female Teleost Poecilia formosa and Poecilia sphenops

Nature, 1968
THE Amazon molly, Poecilia formosa (Girard), is an all-female species native to southern Texas and north-eastern Mexico1. In the northern part of the range, P. formosa is fertilized by males of P. latipinna; in the southern part by a species of the P. sphenops complex. Reproduction is usually by gynogenesis; no introgression of paternal characters into

Nucleoprotein cytochemistry during oogenesis in a unisexual fish,Poecilia formosa

The Histochemical Journal, 1981
Cytochemical methods and electron microscopy were used to study changes in the chemical composition of nuclear, nucleolar and perinuclear bodies during the early stages of oocyte development in Poecilia formosa, an apomictic species of fish that produces only female offspring.

A Sexual Preference in the Amazon Molly, Poecilia formosa

Environmental Biology of Fishes, 1999
The Amazon molly, Poecilia formosa, is an all-female species that reproduces by gynogenesis, i.e., it relies on sperm of males of closely related species to trigger embryogenesis. Sperm is supplied by males of P. latipinna and P. mexicana. Amazon mollies live in sympatry with at least one of these species, a few populations live in sympatry with two ...

Biogeography of the Amazon molly, Poecilia formosa

Journal of Biogeography, 2002
AimThe unisexual Amazon molly (Poecilia formosa) is a clonal, all‐female fish but depends on sperm of heterospecific males to trigger embryogenesis. Thus, one very important factor shaping its geographical range is the presence of suitable host males.

The complete mitochondrial genome of Poecilia formosa (Actinopterygii: Cyprinodontiformes: Poeciliidae)

Mitochondrial DNA Part A, 2015
The complete mitochondrial genome sequence of the Poecilia formosa is first reported in this study. The length of genome is 16 550 bp, including 13 protein-coding genes, 2 ribosomal RNA genes and 22 transfer RNA genes. Congeneric mitogenome sequence identity is 87.7% with P. reticulate and 93.1% with P. sphenops.

Evolutionary Genetics of a Gynogenetic Fish, Poecilia formosa, the Amazon Molly

Evolution, 1980
The application of allozyme and other genetic techniques to the study of unisexual vertebrates has led to the realization that all or nearly all of them possess genomes with a relatively high proportion of loci essentially fixed in the heterozygous state (e.g., Parker and Selander, 1976; Schultz, 1977; Vrijenhoek et al., 1977, 1978); this is apparently

The complete mitochondrial genome of the Poecilia formosa (Amazon molly)

Mitochondrial DNA Part A, 2015
The Amazon molly, Poecilia formosa, a member of the Poeciliidae family, is a freshwater fish reproducing through gynogenesis. The complete mitochondrial genome of the P. formosa is determined for the first time in this study. It is a circular molecule of 16 542 bp in length, including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA ...

Ultraviolet carcinogenesis in the teleost fish, Poecilia formosa

Medical Hypotheses, 1980
A calculation is made of the fraction of a population of Poecilia formosa, that develop ultraviolet induced tumors and the result compared with the experimental data. Reasonable correlation is obtained.
