In humans, the sex of the baby is determined by the sperm. The sperm gamete is heterogamatic because approximately half of them contain the X chromosome which will result in a girl and approximately half of them contain the Y chromosome which will result in a boy.

The female gamete determines the sex because only the egg provides cytoplasm to the zygote. The female gamete determines the sex because only the egg can have one of two functional sex chromosomes. The male gamete determines the sex because it may contribute either an X or a Y chromosome. The male gamete determines the sex because the female sex chromosomes are dormant in the zygote. Sex Determination: Sex determination is the process in many different organisms where an offspring The sex of a human baby is determined by the composition of its sex chromosomes (a single distinct pair among humans' 23 pairs of chromosomes). Females possess two copies of the same chromosome (referred to as the 'X' chromosome); males have one copy of the X chromosome and one copy of the smaller, hook-shaped Y chromosome.

Pair 23 are the sex chromosomes. They carry genes that determine an embryo's sex - whether offspring are male or female: males have two different sex chromosomes, XY females have two X chromosomes, In humans and many other species of animals, the father determines the sex of the child. In the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively. The female gamete determines the sex because only the egg provides cytoplasm to the zygote. The female gamete determines the sex because only the egg can have one of two functional sex chromosomes. The male gamete determines the sex because it may contribute either an X or a Y chromosome.

Determination of Sex in Human Beings! Sex determination in humans: In human beings, sex is determined by genetic inheritance. Genes inherited from the parents determine whether an offspring will be a boy or a girl. Genes for all the characters are linearly arranged on chromosomes. These include the genes for sexual characters.
