Occurrence 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...

متن کاملFurther analysis of negative assortative mating.
HE paper “Ana1ys.k of models with homozygote x heterozygote matings“ was devoted to the complete mathematical analysis of the equilibrium behavior of some models proposed by SCUDO (1964) and FINNEY (1952) and some of their qualitative implications for population genetics in general. In this paper we repeat this process with certain models described by WORKMAN ( 1964), NAYLOR (1962) and others. ...
متن کاملA 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...
