A human body cell would have 46 chromosomes. Since a human egg cell is a reproductive cell (sex cell), it would contain only half the number of chromosomes as a body cell. Thus, a human egg cell would have 23 chromosomes. A sex cell has half the number of chromosomes for a good reason. When two sex cells reproduce, they combine to form double the number of chromosomes. So when two cells with 23 chromosomes each reproduce, the offspring would have 46 chromosomes.
Chromosomes are arrangements of genes made from DNA. Most of the chromosomes of plants and animals are arranged in pairs. The number of chromosomes varies among organisms. Humans typically have 46, a rice plant has 12, a fruit fly, 4. During human reproduction, both the egg and sperm donate 23 chromosomes to the fertilized egg, the zygote, for a total of 23 pairs. Each pair of chromosomes has one allele from each parent for every gene.
