How many chromosomes are typically found in a normal human body cell?

Explanation

A typical human somatic, or body, cell contains 46 chromosomes, arranged in 23 pairs, with one set inherited from each parent. Reproductive cells, meaning sperm and egg, contain only 23 chromosomes each, so that when they combine during fertilization the resulting embryo has the full 46. Conditions like Down syndrome occur when there is an extra copy of a chromosome, such as chromosome 21. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
