Horses have 64 chromosomes and donkeys have 62 chromosomes, together they produce mules with 63 chromosomes. If we were to take a sperm cell or an egg from a person with either XXYY, XXXY, or XXXX syndrome and then taken a sperm cell or egg from a chimpanzee and used in vitro fertilization, would this produce a human-chimpanzee hybrid? Chimpanzees have 48 chromosomes and humans have 46 chromosomes, therefore together they might produce humanzees.
Also: would it be possible to genetically engineer an immortal cell line of human sperm cells capable of growing as large as the species Valonia ventricosa and keep the giant sperm cells alive and fed in an aquarium? Would it be possible to use radiation (or whatever) in order to cause the cells to mutate like HeLa cells? Having your sperm cells been genetically modified so that they grow to be two to three inches long or longer and can survive for several years outside of your body so that you can keep them as pets in a tank? Or farm them for food?
