Chromosomes are thread-like structures in cells containing DNA. They carry genetic information, determining an organism’s traits. Humans have 23 pairs, with one set inherited from each parent.

Chromosomes are thread-like structures in cells containing DNA. They carry genetic information, determining an organism’s traits. Humans have 23 pairs, with one set inherited from each parent.
A zygote is formed by the fusion of a sperm cell and an egg cell during fertilization. Each of these parent cells contributes a set of chromosomes to the zygote. Humans are diploid organisms, meaning they have two sets of chromosomes—one set from each parent. Therefore, a zygote, being the initial cell formed by fertilization, is also diploid and contains two sets of chromosomes. In humans, the diploid number of chromosomes is typically 46, with 23 chromosomes inherited from the mother and 23 chromosomes inherited from the father.
