A sex chromosome; normal males carry one Y and one X chromosome.
One of the sex chromosomes. Males have one Y chromosome; females have none.
The Y chromosome is the chromosome that makes a person a male and can be passed by a male only to his sons. It differs from all other chromosomes that the majority of the chromosome is unique and does not recombine during meiosis (see NRY or non-combining Y). This means the historical pattern of mutations can easily be studied.
the sex chromosome that is carried by men; "human males normally have one X chromosome and one Y chromosome"
sex chromosome that confers maleness in humans, when present in the cell. A normal complement for males is a X and a Y chromosome (XY) (see also X Chromosome).
The sex chromosome that distinguishes males (XY) from females (XX).
A chromosome in a sperm cell that carries male genetic material. Men release male and female (X and Y chromosomes) genetic material and therefore determine the sex of the child.
A sex chromosome. An X and a Y chromosome comprise a male.
The Y chromosome contains male-specific genes from the father. Sperm carry X or Y chromosomes: if an egg is fertilised by a sperm that has a Y chromosome a boy will be born, if the sperm has an X chromosome a girl will be born. to top of page
The male sex chromosome in species in which males have two sex chromosomes that differ to one another.
One of the two sex chromosomes; determines male sex characteristics.
one of the chromosomes that determines sex. Males carry one X chromosome and one Y chromosome in each somatic cell.
The Male chromosome Males have one Y and one X chromosome in their genotype.
The genetic material that transmits the information necessary to make a male. The Y chromosome can be found in one half of the man's sperm cells. When an X and a Y chromosome combine, the baby will be a boy.
The chromosome that determines male gender.
The Y chromosome is one of the sex-determining chromosomes in humans and most other mammals. In mammals, it contains the gene SRY, which triggers testis development, thus determining maleness.
