Whether they have 2 X chromosomes= girl,
of one X chromosome and one Y chromosome= boy
The genes that are carried in the sperm to the ova. If the 23rd chromosome of the sperm is 'X', the offspring will be female. If it is 'Y', the offspring will be male.
The biological sex of a human is determined by the combination of sex chromosomes in the human's cells. XX is the genotype of females, and XY the genotypes of males.
Normal male humans have the sex chromosomes XY. The presence of the Y chromosome determines sex in humans - so a person with XXY will be male.
a typical human have 26 pairs of chromosomes in their cell.26th pair is called sex chromosome and it determines the sex of an individual, and those are denoted am X and Y. Males have sex chromosome in the combination XY and females XX.
In humans, which sex chromosome determines if an offspring is a male or female?
The male and female each contribute 23 chromosomes, one of which determines the sex of the baby/new human
The human male has both an X and Y chromosome which determines the sex of an offspring. Female only have the X chromosome.
the answer is sex chromosomes

the father
The human male has both an X and Y chromosome which determines the sex of an offspring. Female only have the X chromosome.
Human eggs usually have one X chromosome. The mother has only two X's and can't give the egg any other than a X. The male determines the sex of the zygote since he will give either a Y or X.
The male has an x and a y sex chromosome. The female has two x sex chromosomes.
