In humans, the presence of the Y chromosome is responsible for triggering male development; in the absence of the Y chromosome, the fetus will undergo female development. In most species with XY sex determination, an organism must have at least one X chromosome in order to survive. [2] [3]
The development of sexual differences begins with the XY sex-determination system that is present in humans, and complex mechanisms are responsible for the development of the phenotypic differences between male and female humans from an undifferentiated zygote. [3] Females typically have two X chromosomes, and males typically have a Y ...
A third-person pronoun is a pronoun that refers to an entity other than the speaker or listener. [1] Some languages, such as Slavic, with gender-specific pronouns have them as part of a grammatical gender system, a system of agreement where most or all nouns have a value for this grammatical category.
Gender identity (despite what the gender binary suggests) does not have to match one's sex assigned at birth, and it can be fluid rather than fixed and change over time.
Gender systems are the social structures that establish the number of genders and their associated gender roles in every society. A gender role is "everything that a person says and does to indicate to others or to the self the degree that one is either male, female, or androgynous. This includes but is not limited to sexual and erotic arousal ...

Donald Trump’s victory was helped in no small part by the unexpected shift of support he received among Gen Z voters. While voters under the age of 30 still broke for Kamala Harris, her margin ...
The human Y-chromosome has had about 5 strata since the origin of the X and Y chromosomes about 300 Mya from a pair of autosomes. Each stratum was formed when a pseudoautosomal region (PAR) of the Y chromosome is inverted, stopping it from recombination with the X chromosome. Over time, each inverted region decays, possibly due to Muller's ratchet.
