XY
A male human has one X and one Y sex chromosome.
The male human is represented by a sex chromosome consisting of one X chromosome and one Y chromosome (XY).
The male sex chromosome is XY, and females are XX. The X comes from the female, and an X or a Y from the male. When they meet, that determines whether the baby will be a boy or a girl.
Male sex chromosomes are the X and Y chromosomes. The presence of a Y chromosome typically determines male biological sex, while the absence of a Y chromosome typically results in female biological sex. The combination of sex chromosomes inherited from parents determines an individual's biological sex.
The male chromosome is officially known as the Y chromosome.
In humans, which sex chromosome determines if an offspring is a male or female?
X chromosome
A boy typically results from the combination of an X chromosome from the mother and a Y chromosome from the father, creating a male offspring with the genetic makeup XY. This combination determines the male sex in humans. The presence of the Y chromosome triggers the development of male characteristics during embryonic development.
Y chomozomes, I think. It says on Wikipedia.

Y
Maleness is not a genotype but a combination of sex chromosomes. A normal human male has an X as well as a Y chromosome.
