Sex chromosome: a chromosome involved with determining the sex of an individual. In animals and plants that have evolved separate sexes, accurate differentiation into fertile males and females is a fundamental developmental process. Gynodioecy: a breeding system that consists of a mixture of females and hermaphrodites.

Sequencing DNA from pools of male and female progenies of a single cross will identify sex-specific nucleotide differences. Vicoso B, Kaiser VB, Bachtrog D Sex-biased gene expression at homomorphic sex chromosomes in emus and its implication for sex chromosome evolution.

The cause of directional selection during the evolutionary rise of csd is not understood and cannot be explained by an adjustment of sex ratios or an intra-locus sexual conflict.

Many fish and some gastropods and plants are sequential hermaphrodites ; clownfish, for example, are born males and change into females, while many wrasses or gobies begin life as females and then change to males.

  • A sex-determination system is a biological system that determines the development of sexual characteristics in an organism.
  • A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most sexual organisms have two sexes.
  • A sex-determination system is a biological system that determines the development of sexual characteristics in an organism.
  • A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most common sex-determination systems in animals involve a genetic mechanism based on the chromosomes of that organism.
  • A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most organisms that create their offspring using sexual reproduction have two sexes.
  • Sex determination , the establishment of the sex of an organism, usually by the inheritance at the time of fertilization of certain genes commonly localized on a particular chromosome. This pattern affects the development of the organism by controlling cellular metabolism and stimulating the production of hormones that trigger the development of sexual glands or organs.

According to the rapid evolution of sex-determination systems hypothesis, research in some species of Ellobius moles and the spiny rat Tokudaia have confirmed that SRY is no longer responsible for determining masculinity, as it does not occur in the Y chromosome the karyotypes for males and females being the same, XO in E.
