What it means
One of each pair comes from each parent. The count is not a measure of complexity: a dog has seventy eight and some ferns have well over a thousand. Egg and sperm cells carry half the number, so a fertilized cell arrives back at the full complement. An extra copy of even one chromosome usually has serious consequences, which is what makes Down syndrome a trisomy.
The claim comes from National Human Genome Research Institute.
