A RAD-tag genetic map for the platyfish (Xiphophorus maculatus) reveals mechanisms of karyotype evolution among teleost fish.
Mammalian genomes can vary substantially in haploid chromosome number even within a small taxon (e.g., 3-40 among deer alone); in contrast, teleost fish genomes are stable (24-25 in 58% of teleosts), but we do not yet understand the mechanisms that account for differences in karyotype stability. Among perciform teleosts, platyfish (Xiphophorus maculatus) and medaka (Oryzias latipes) both have 2...
متن کاملGenetic linkage and color polymorphism in the southern platyfish (Xiphophorus maculatus): a model system for studies of color pattern evolution.
Color pattern polymorphisms are widespread in animals, and are found within populations, among populations, and among species. The southern platyfish, Xiphophorus maculatus, represents one of the most extreme examples of color pattern polymorphism. Extensive research with this model system for melanoma formation has resulted in an understanding of the underlying genetic basis of over 40 sex-lin...
متن کاملOccurrence and histopathology of Ascocotyle tenuicollis metacercaria in gill of platyfish (Xiphophorus maculatus) imported to Iran
The objective of this study was to determine the prevalence of metacercarial infection in plathyfish imported to Iran. A total of 100 imported live common platyfish (Xiphophorus maculatus) from approximately 24 shipments were collected from a quarantine facility in Iran in 2007 and examined in our veterinary laboratory. Among 800 examined gill arches about 1300 cysts were found in different loc...

متن کاملCloning of the dmrt1 gene of Xiphophorus maculatus: dmY/dmrt1Y is not the master sex-determining gene in the platyfish.
In contrast to the situation observed in mammals and birds, a switching between different sex determination systems frequently occurred during the evolution of the teleost fish lineage. This might be due to a frequent turnover of sex-determining signals at the top of the sex determination cascade (master sex-determining genes in the case of genetic sex determination). Alternatively, different v...
