XX = female. XY= male because the Y chromosome has SRY gene (Sex-deterimining Region Y). The SRY gene in mammals makes the body produce testis which makes testosterone making the foetus male. For more information, please see the related link below.
The Y chromosome carries the SRY gene (Sex-determining Region Y) which is essential for male sexual development. The SRY gene triggers the development of male sex characteristics during fetal development.
Males determine the sex of a child in humans because they carry both X and Y chromosomes, while females carry two X chromosomes. During fertilization, the sperm from the male can carry either an X or a Y chromosome, determining the sex of the child.
The father determines the sex of the baby in humans. Sperm cells contain either an X or Y chromosome, and the sperm that fertilizes the egg will determine the sex of the baby. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.
One X chromosome and one Y chromosome, which determines male sex characteristics.
Sex chromosomes are a pair of chromosomes that determine an individual's biological sex. In humans, females typically have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome triggers the development of male characteristics, while the absence of the Y chromosome results in the development of female characteristics.
Y chromosome.
The Y chromosome carries the SRY gene (Sex-determining Region Y) which is essential for male sexual development. The SRY gene triggers the development of male sex characteristics during fetal development.
Maleness is not a genotype but a combination of sex chromosomes. A normal human male has an X as well as a Y chromosome.
Males determine the sex of a child in humans because they carry both X and Y chromosomes, while females carry two X chromosomes. During fertilization, the sperm from the male can carry either an X or a Y chromosome, determining the sex of the child.
Chromosome pair 23 in humans is the pair of sex chromosomes. In females, both sex chromosomes are the X sex chromosome, and in human males one sex chromosome is the X and the other is the Y chromosome.
The father determines the sex of the baby in humans. Sperm cells contain either an X or Y chromosome, and the sperm that fertilizes the egg will determine the sex of the baby. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.
In humans, males have one Y chromosome and one x chromosome in addition to 44 other chromosomes, females have two Xs. Because of errors in gamete (egg or sperm) production, some humans have XYY, XXY, or some other combination of sex chromosomes.
One X chromosome and one Y chromosome, which determines male sex characteristics.
The y chromosome. The chromosome pair that determine sex (gender) can have x and y chromosomes; men have one X and one Y chromosome, women have to X chromosomes.
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
In humans, the Y chromosome is noticeably shorter than the X chromosome.
In humans the male sperm contains EITHER an X chromosome, or a Y chromosome since human gametes are haploid (n) in chromosome number.
