Sexual dimorphism in body weight, fat distribution, and metabolic disease has been attributed largely to differential effects of male and female gonadal hormones. Here, we report that the number of X chromosomes within cells also contributes to these sex differences. We employed a unique mouse model...

The Newcastle University study suggests that an as-yet undiscovered gene controls whether a man’s sperm contains more X or more Y chromosomes, which affects the sex of his children. On a larger scale, the number of men with more X sperm compared to the number of men with more Y sperm ...
Women live longer than men with Alzheimer's because their sex chromosomes give them genetic protection from the ravages of the disease. Women get two 'doses' of a gene that only exists on the X chromosome. And some people, both male and female, have an especially potent variant of this ...
The avian ZW system is quite the reverse of the well-studied mammalian XY chromosome system, and evolved independently from different autosomal blocs. Despite the different gene content of mammal and bird sex chromosomes, there are many parallels. Genes on the bird Z and the mammal X have both...
In this respect, one of the most understudied groups is the family Helodermatidae (Anguimorpha) encompassing the only two venomous species of lizards which are potentially lethal to human beings. We uncovered homomorphic ZZ/ZW sex chromosomes in the Gila monster (Heloderma suspectum) with a ...
In Drosophila melanogaster both sex determination and dosage compensation are governed by the ratio of the number of X chromosomes to sets of autosomes. We propose a mechanism by which this ratio can be measured at the cellular level. The mechanism helps in understanding the effects of, and inte...

This is problematic on a number of levels. I play dumb, of course—what else can I do? “Maybe she went to GenLab,” I say. “Her? You’re kidding me, right? I mean, look at that string of jerks she keeps dating. If you want to know the truth, she’s lower-class, Roy, an...
