Biochemical systematics of the viviparous fish family Goodeidae
Journal of Fish Biology, 1992The systematic relationships of the freshwater teleost family Goodeidae inferred from a distance Wagner analysis of allozyme data are mainly consistent with previous systematic hypotheses, including some of those based on karyology. However, a recently proposed hypothesis based on bony anatomy of the mouth is not supported.

Branchial placenta in the viviparous teleost Ilyodon whitei (Goodeidae)
Journal of Morphology, 2014ABSTRACTIntraluminal gestation, as it occurs in viviparous goodeids, allows a wide diversity of embryo‐maternal metabolic exchanges. The branchial placenta occurs in embryos developing in intraluminal gestation when ovarian folds enter through the operculum, into the branchial chamber.

REPRODUCTIVE ASPECTS OF GIRARDINICHTHYS MULTIRADIATUS, MEEK 1904 (PISCES: GOODEIDAE)
BIOCYT Biología Ciencia y Tecnología, 2020<p>This paper discusses biology reproductive aspects of the yellow fish <em>G. multiradiatus </em>in the reservoir of Villa Victoria located in the State of Mexico, Mexico. Monthly samplings were carried from November, 2005 to October, 2006. 657 organisms were collected using a baitwell net.

Copeia, 1984
Allozyme survey of 15 polymorphic loci in four Ilyodon populations from a tributary of the Rio Coahuayana, Jalisco, Mexico, revealed marked interlocality populational differences, but striking within-locality similarities between two trophic morphotypes which once were considered different species.

Morphological variation in vanishing Mexican desert fishes of the genus Characodon (Goodeidae)
Journal of Fish Biology, 2014This study investigated a rapidly vanishing group of fishes in the genus Characodon (including Characodon lateralis and Characodon audax) from the upper Rio Mezquital drainage in Mexico. Using specimens from museum collections, morphological variation was assessed to quantify body shape differentiation among historic (i.e.

Genomic patterns of divergence and gene flow in Drosophila and Goodeidae
2023Understanding the impact of the presence or absence of geographic barriers on speciation has been a source of enduring interest in evolutionary biology. The degree of geographical isolation and the prevalence of gene flow during divergence may often determine the rate of reproductive isolation and the relative importance of other evolutionary forces ...

Molecular systematics of the genus Allodontichthys (Cyprinodontiformes: Goodeidae)
Reviews in Fish Biology and Fisheries, 2002Phylogenetic analyses of cytochrome c oxidasesubunit I (627bp) and mitochondrial controlregion (338bp aligned) sequences for all knownspecies of Allodontichthys wereperformed. Allodontichthys was recoveredas monophyletic, and A. hubbsi wassupported as the most primitive member of thegenus in all analyses. Combined-data analysessuggest that A. polylepis
