The egg has 23, and the sperm has 23 (leading to 46 total, in 23 pairs) However, genetically, the sperm and egg each only have one. The egg has an "X" chromosome, and the sperm has either an "X" or a "Y" chromosome. So, that means they only have 1 chromosome each.
WebDec 24, 2024 · Bacterial genomes can range in size anywhere from 139 kbp to 13,000 kbp.
