Most therian mammals have only one pair of sex chromosomes in each cell.
Males have one Y chromosome and one X chromosome, while females have two X chromosomes.
In mammals, the Y chromosome contains a gene, SRY, which triggers embryonic development as a male.

What is the gender of YY?
Males typically have two different kinds of sex chromosomes (XY), and are called the heterogametic sex. 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.
Can a female be born with XY chromosome?
XY gonadal dysgenesis, also known as Swyer syndrome, is a type of hypogonadism in a person whose karyotype is 46,XY. They typically have normal female external genitalia, identify as female, and are raised as girls.
What makes a male a male?
A male (♂) organism is the physiological sex that produces sperm. Each spermatozoon can fuse with a larger female gamete, or ovum, in the process of fertilization.
In general, traits that exist on the Y chromosome are Y-linked because they only occur on that chromosome and do not change in recombination.
Does sperm have a gender?
Female sperm can refer to either: A sperm which contains an X chromosome, produced in the usual way by a male, referring to the occurrence of such a sperm fertilizing an egg and giving birth to a female. A hypothetical sperm which artificially contains genetic material from a female.
Can a woman have Y chromosome?
Males have one Y chromosome and one X chromosome, while females have two X chromosomes. In mammals, the Y chromosome contains a gene, SRY, which triggers embryonic development as a male. The Y chromosomes of humans and other mammals also contain other genes needed for normal sperm production.

Chromosomal sex is determined at the time of fertilization; a chromosome from the sperm cell, either X or Y, fuses with the X chromosome in the egg cell. Gonadal sex refers to the gonads, that is the testis or ovaries, depending on which genes are expressed.
