    en.wikipedia.org/wiki/Sex_chromosome

    Sex chromosomes (also referred to as allosomes, heterotypical chromosome, gonosomes, heterochromosomes, [ 1 ][ 2 ] or idiochromosomes[ 1 ]) are chromosomes that carry the genes that determine the sex of an individual. The human sex chromosomes are a typical pair of mammal allosomes. They differ from autosomes in form, size, and behavior.

    The human Y chromosome showing the SRY gene which codes for a protein regulating sexual differentiation. Sexual differentiation in humans is the process of development of sex differences in humans. It is defined as the development of phenotypic structures consequent to the action of hormones produced following gonadal determination. [1]

  6. Sex verification in sports - Wikipedia

    en.wikipedia.org/wiki/Sex_verification_in_sports

    Sex verification in sports (also known as gender verification, or as gender determination or a sex test) occurs because eligibility of athletes to compete is restricted whenever sporting events are limited to a single sex, which is generally the case, as well as when events are limited to mixed-sex teams of defined composition (e.g., most pairs ...

  7. Homologous chromosome - Wikipedia

    en.wikipedia.org/wiki/Homologous_chromosome

    Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. One homologous chromosome is inherited from the organism's mother; the other is inherited from the organism's father. After mitosis occurs within the daughter cells, they ...

  8. Sex differences in human physiology - Wikipedia

    en.wikipedia.org/wiki/Sex_differences_in_human...

    Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These differences are caused by the effects of the different sex chromosome complement in males and females, and differential exposure to gonadal sex hormones during development. Sexual dimorphism is a term for the ...

  9. X chromosome - Wikipedia

    en.wikipedia.org/wiki/X_chromosome

    The X chromosome is one of the two sex chromosomes in many organisms, including mammals, and is found in both males and females. It is a part of the XY sex-determination system and XO sex-determination system. The X chromosome was named for its unique properties by early researchers, which resulted in the naming of its counterpart Y chromosome ...
