In humans females are homogametic and males are heterogametic. It is the male biological parent who contributes the sex chromosome that determines the sex of any child.
Human females are XX and all their ova carry an X chromosome. Females always give their children an X chromosome.
Human males are XY and half their spermatozoa carry an X chromosome and half carry a Y chromosome. Depending on the sex chromosome in its biological father's spermatozoon, a child receives an X or a Y chromosome from its biological father.
If a child receives an X chromosome from its father she will be XX and a girl. If a child receives a Y chromosome from its father he will be XY and a boy.

The genes that determines gender can be found in the Y chromosome.
What does the x and the y choromosome determine?
it determines the gender of a human being
What determines which allele of each pair goes into a gamete?
The process of allele segregation during gamete formation is determined by the random assortment of chromosomes during meiosis. Homologous pairs of chromosomes separate independently, and each resulting gamete randomly receives one copy of each chromosome. This random assortment leads to the random segregation of alleles, determining which allele of each pair goes into a gamete.
How does the male gamete in flowers differ to animal gamete?
Male gamete in flowers is pollen grain that produce in anther . When male gamete in animal is sperm that produce by testes
Who makes the sex of the baby?
The chromosome in the male's gamete determines the gender of the baby. If it is a Y chromosome, the baby will be a boy. If the chromosome is a X, the baby will be a girl.
If a human gamete with an extra chromosome participated in fertilization with a normal human gamete what condition results?
A trisomy. Trisomies are usually fatal in all chromosome pairs except 5, 13, 21 (these cause Down syndrome), and 23 (The chromosome pair that determines gender)
