Verified step by step guidance1
Recall that human somatic (body) cells are diploid, meaning they contain two sets of chromosomes, one from each parent, totaling 46 chromosomes.
Understand that meiosis is the process by which diploid cells divide to produce haploid gametes (sperm and egg cells), reducing the chromosome number by half.
Recognize that after meiosis is complete, each mature egg cell (ovum) contains only one set of chromosomes, which is half the diploid number.
Calculate the haploid number by dividing the diploid number (46) by 2, using the formula: \(\frac{46}{2} = 23\).
Conclude that a mature human egg cell contains 23 chromosomes after meiosis is complete.
