Sex-Determination and Sex-Differentiation in Mammals.
only when the compound capable of tautomerization is in the liquid phase, or in solution. And that is just the case with the free radicals under consideration. 6. The two radicals, a-naphthyl-diphenylmethyl and a-naphthylxanthyl, were found to give a molecular weight less than that calculated for the monomolecular phase. Schlenk and Renning's" results show that a-naphthyl-biphenyl-phenylmethyl ...
متن کاملDiversity and plasticity of sex determination and differentiation in fishes.
Among vertebrates, fishes show an exceptional range of reproductive strategies regarding the expression of their sexuality. Fish sexualities were categorized into gonochorism, synchronous/sequential hermaphrodite, or unisexual reproduction. In gonochoristic fishes, sex is determined genetically or by environmental factors. After sex determination, the gonads are differentiated into ovary or tes...

Reproduction in domestic animals, as a major source of food and other products for human, has greatimportance and study of related subjects including sex differentiation and gonadogenesis during fetal life can solve many questions on normal development and various disorders of urogenital system. Since studies on sex differentiation in goat fetus are scarce, this study was performed. Twenty-five...

N Engl J Med 2004;350:367-78. Copyright © 2004 Massachusetts Medical Society. ex determination, which depends on the sex-chromosome complement of the embryo, is established by multiple molecular events that direct the development of germ cells, their migration to the urogenital ridge, and the formation of either a testis, in the presence of the Y chromosome (46,XY), or an ovary in the absence o...
متن کاملThe past, present, and future of sex segregation methodology.
We review the logic underlying margin-free analyses of sex segregation arrays. In the course of our review, we show that the Karmel-MacLachlan decomposition does not live up to its margin-free billing, as the index upon which it rests, Ip, is itself margin-sensitive. Moreover, because the implicit individualism of D is necessarily inconsistent with margin-free analysis, the field would do well ...
