Question

how is the sex of child determined in human beings?​

Answer 1

Answer:

by chromosomes

Explanation:

every human has 23 pairs of chromosomes

the last pair of chromosomes is named as sex chromosmes

Sex of child in humans is determined by the type of male haploid gamete that fuses with the female egg. ... So if the male gamete with the X chromosome fuses with the female egg, the child will be female and if the male gamete with the Y chromosome fuses with the female egg, the child will be male.

Answer 2

Human beings have 46 chromosomes in the nuclei of their cells. out of these 44 are known as autosomes and the last pair is termed as sex chromosomes. During fertilisation if an egg fuses with a (22+y) sperm, the resultant zygote will develop into a male child; If an egg fuses with a (22+x) sperm, resultant zygote will develop into a female child. After this, Father and Mother is responsible for determining the sex of the child.
