Vertebrate sex-determining genes play musical chairs
Sexual reproduction is one of the most highly conserved processes in evolution. However, the genetic and cellular mechanisms making the decision of whether the undifferentiated gonad of animal embryos develops either towards male or female are manifold and quite diverse. In vertebrates, sex-determining mechanisms range from environmental to simple or complex genetic mechanisms and different mec...
متن کاملComparative In silico Study of Sex-Determining Region Y (SRY) Protein Sequences Involved in Sex-Determining
Background: The SRY gene (SRY) provides instructions for making a transcription factor called the sex-determining region Y protein. The sex-determining region Y protein causes a fetus to develop as a male. In this study, SRY of 15 spices included of human, chimpanzee, dog, pig, rat, cattle, buffalo, goat, sheep, horse, zebra, frog, urial, dolphin and killer whale were used for determine of bioi...
متن کاملSex-determining genes in the homosporous fern Ceratopteris.
Haploid Ceratopteris gametophytes are either hermaphroditic or male. The determinate of sex type is the pheromone antheridiogen (ACE) which is secreted by the meristic hermaphrodite and promotes ameristic male development of sexually undetermined gametophytes. Several mutations effecting the sex of the haploid gametophyte have been isolated and are described. The hermaphroditic (her) mutants ar...
متن کاملSex from W to Z: evolution of vertebrate sex chromosomes and sex determining genes.
Sex determination in major vertebrate groups appears to be very variable, including systems of male heterogamety, female heterogamety and a variety of genetic and environmental sex determining systems. Yet comparative studies of sex chromosomes and sex determining genes now suggest that these differences are more apparent than real. The sex chromosomes of even widely divergent groups now appear...
متن کاملRapid Coevolution of the Nematode Sex-Determining Genes fem-3 and tra-2
Unlike many features of metazoan development, sex determination is not widely conserved among phyla. However, the recent demonstration that one gene family controls sexual development in Drosophila, C. elegans, and vertebrates suggests that sex determination mechanisms may have evolved from a common pathway that has diverged radically since the Cambrian. Sex determination gene sequences often e...
