The question
Quick question- sperm and egg cells, don' t they contain 23 chromosomes only as they are germ cells (Haploid cells) , and not 2x 23 as mentioned in this article?
Answer from Dr. Geoffrey Sher
Both sperm and eggs start off with 46 chromosomes. Then during meiosis (reproductive maturational division, the divide their chromosomes in half to 23 (the haploid number). The fusion of the sperm and the egg thereupon reconstitutes the chromosomes in the embryo to 46(the diploid number).
