the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
An Estimate of the Number of Histocompatibility Loci in the Teleost Xiphophorus Maculatus.
vigorous immune response against tissue homografts is characteristic of A nearly all postembryonic vertebrates. The homograft reaction has been demonstrated in all species of teleosts tested (KALLMAN 1964; HILDEMANN and HAAS 1960), and in many amphibians (HILDEMANN and HAAS 1959; VOGEL 1940; HOROWITZ 1937), in at least one reptile (MAY 1923), several birds (HEALEY, RUSSEL, POOLE and OLSEN 1962;...

sex-determining mechanism in Poeciliid fishes of the genus Xiphophorus ' F : been studied for more than forty years (BELLAMY 1928; GORDON 1927), yet many problems remain unsolved. In the southern platyfish, Xiphophorus maculatus, native to Mexico and adjacent parts of Central America, there are three types of females (XX, WX, WY) and two types of males (XY and YY) (GORDON 1947, 1954; KALLMAN 19...
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...
