  2. Hermaphrodite - Wikipedia

    en.wikipedia.org/wiki/Hermaphrodite

    Animal species in which individuals are either male or female are gonochoric, which is the opposite of hermaphroditic. [2] The individuals of many taxonomic groups of animals, primarily invertebrates, are hermaphrodites, capable of producing viable gametes of both sexes.

  3. Intersex (biology) - Wikipedia

    en.wikipedia.org/wiki/Intersex_(biology)

    Intersex is a general term for an organism that has sex characteristics that are between male and female. [1] It typically applies to a minority of members of gonochoric animal species such as mammals (as opposed to hermaphroditic species in which the majority of members can have both male and female sex characteristics). [2]

  4. Intersex - Wikipedia

    en.wikipedia.org/wiki/Intersex

    Most animal species (~95%, including humans) are gonochoric, in which individuals are of either a female or male sex. [186] Hermaphroditic species (some animals and most flowering plants [ 187 ] ) are represented by individuals that can express both sexes simultaneously or sequentially during their lifetimes. [ 188 ]

  5. Gonochorism - Wikipedia

    en.wikipedia.org/wiki/Gonochorism

    In biology, gonochorism is a sexual system where there are two sexes and each individual organism is either male or female. [1] The term gonochorism is usually applied in animal species, the vast majority of which are gonochoric. [2]: 212–222

  6. Simultaneous hermaphroditism - Wikipedia

    en.wikipedia.org/wiki/Simultaneous_hermaphroditism

    Simultaneous hermaphroditism is one of the two types of hermaphroditism, the other type being sequential hermaphroditism.In this form of hermaphroditism an individual has sex organs of both sexes and can produce both gamete types [1] even in the same breeding season.

  7. Sexual dimorphism - Wikipedia

    en.wikipedia.org/wiki/Sexual_dimorphism

    The term sesquimorphism (the Latin numeral prefix sesqui- means one-and-one-half, so halfway between mono- (one) and di- (two)) has been proposed for bird species in which "both sexes have basically the same plumage pattern, though the female is clearly distinguishable by reason of her paler or washed-out colour".

  8. Sex-determination system - Wikipedia

    en.wikipedia.org/wiki/Sex-determination_system

    Transcaucasian mole voles (Ellobius lutescens) also have a form of XO determination, in which both sexes lack a second sex chromosome. [11] The mechanism of sex determination is not yet understood. [21] The nematode C. elegans is male with one sex chromosome (X0); with a pair of chromosomes (XX) it is a hermaphrodite. [22]

  9. Sequential hermaphroditism - Wikipedia

    en.wikipedia.org/wiki/Sequential_hermaphroditism

    Those that change gonadal sex can have both female and male germ cells in the gonads or can change from one complete gonadal type to the other during their last life stage. [ 7 ] In plants, individual flowers are called dichogamous if their function has the two sexes separated in time, although the plant as a whole may have functionally male ...
