SRY, the mammalian Y-chromosomal testis-determining gene, induces male sex
determination. Recent studies in mice reveal that the major role of SRY is to achieve …

Most animals are sexually dimorphic, but different taxa have different sex-specific traits.
Despite major differences in the genetic control of sexual development among animal …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Sex in mammals is genetically determined and is defined at the cellular level by sex
chromosome complement (XY males and XX females). The Y chromosome–linked gene sex …

A major transition during development of the gonad is commitment from an undifferentiated
“bi-potential” state to ovary or testis fate. In mammals, the oogonia of the develo** ovary …

Insects exhibit a variety of sex determining mechanisms including male or female
heterogamety and haplodiploidy. The primary signal that starts sex determination is …

The study of sex determination and sex chromosome organization in nonmodel species has
long been technically challenging, but new sequencing methodologies now enable precise …

Abstract The Pacific halibut (Hippoglossus stenolepis) is a key species in the North Pacific
Ocean and Bering Sea ecosystems, where it also supports important fisheries. However, the …

In mammals, sex determination defines the differentiation of the bipotential genital ridge into
either testes or ovaries. Sry, the mammalian Y-chromosomal testis-determining gene, is a …

Background Y chromosomes are responsible for the initiation of male development, male
fertility, and other male-related functions in diverse species. However, Y genes are rarely …
