In this process, an X chromosome and a Y chromosome act to determine the sex of offspring, often due to genes located on the Y chromosome that code for maleness. Offspring have two sex chromosomes: an offspring with two X chromosomes (XX) will develop female characteristics, and an offspring with an X and a Y chromosome (XY) will develop male ...
In some species, sex determination is genetic: males and females have different alleles or even different genes that specify their sexual morphology. In animals, this is often accompanied by chromosomal differences, generally through combinations of XY, ZW, XO, ZO chromosomes, or haplodiploidy.
This list of gender identity terms can help. ... People who are intersex are born with a combination of male and female traits, such as differences in genitalia, chromosomes, hormones, and more ...
In a large number of organisms, the sex-determination systems presently observed are products of sex chromosome turnover. Sex chromosome turnover is a process defined as when the type of the sex chromosome changes as a product of a change in the identity of the sex-determining genes (such as by mutation) or by a change in their location. [28]
Sexuality is different from gender identity, too. ... a person born with either some combination of both sex characteristics (genital organs, hormones, chromosomes) or certain genital variations ...
Our society has convinced us that there are just two options for gender identity, "male" and "female," based on biological sex. But in reality, there's more fluidity. Gender identity is on a ...
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 ]
Gender identity is the personal sense of one's own gender. [1] Gender identity can correlate with a person's assigned sex or can differ from it. In most individuals, the various biological determinants of sex are congruent and consistent with the individual's gender identity. [2]
