The disruption of meiotic sex chromosome inactivation (MSCI) has been proposed to be a major developmental mechanism underlying the rapid evolution of hybrid male sterility. We tested this idea by analyzing cell-specific gene expression across spermatogenesis in two lineages of house mice and their sterile and fertile reciprocal hybrids. We found pervasive disruption of sex chromosome gene expr...

This review summarizes the epidemiology of cancer of the female reproductive system and associated lifestyle factors. It also assesses the available evidence for occupational factors associated with these cancers. Cervical, endometrial, and ovarian cancers are relatively common, and cause significant cancer morbidity and mortality worldwide, whereas vulvar, vaginal, fallopian tube cancers, and ...

In farm animals, both genetic and non-genetic factors affect reproductive traits. These can be categorized as intrinsic extrinsic. Extrinsic relate to the animal’s environment, while are related its genotype. Various traits studied concerning age, season, management, nutrition, body score, birth type. addition, variations of transforming growth factor-β (TGFβ) superfamily including BMPR-1B, BMP...
