Female XX sex chromosomes increase survival and extend lifespan in aging mice 来自 EBSCO 喜欢 0 阅读量: 12889 作者:EJ Davis,I Lobach,DB Dubal 摘要: Female longevity is observed in humans and much of the animal kingdom, but its causes remain elusive. Using a genetic manipulation that ...

VIII. An unusual XY/XX-sex chromosome system in Gastrotheca riobambae (Anura, Hylidae). The mitotic and meiotic chromosomes of the marsupial frog Gastrotheca riobambae were analysed with various banding techniques. The karyotype of this species is distinguished by considerable amounts of constitutive...
Supermales (YY sex chromosomes) and androgen-treated XY males: Competition for mating with female killifish B Walter,J Hamilton - 《Animal Behaviour》 被引量: 0发表: 1970年 Population structure, reproduction and laboratory behavior of the introduced Belonesox belizanus (Poeciliidae) in Florida The...
Catfish have an X-Y sex determination system with monomorphic sex chromosomes. Hormonal sex reversal can produce viable XY females which produce XY and YY male offspring when mated with normal XY males. The YY males are phenotypically identical to XY males and must be identified by progeny ...
Evolution of Dosage Compensation in Anolis carolinensis, a Reptile with XX/XY Chromosomal Sex Determination. In species with highly heteromorphic sex chromosomes, the degradation of one of the sex chromosomes will result in unequal gene expression between the sexes (e.g. between XX females and XY...
The 46,XX disorders of sex development (DSDs) cause virilisation or masculinisation of the female foetus. The final common pathway of all 46,XX DSDs is excess dihydrotestosterone (DHT) or potent foreign androgen in the genital tissue during the critical period of sexual differentiation. Whereas ...
acetosa. There were no signs of degeneration of microspores or disturbances in pollen divisions (irregular nuclei, micronuclei, delayed chromosomes and anaphase bridges). The Alexander test revealed only 1.6% nonviable pollen grains within anthers. All mature pollen grains were uniformly equipped with...
