Sperm cells can carry X or Y chromosomes 7 of 21 Human body cells each contain: 23 pairs of chromosomes 8 of 21 To have cystic fibrosis, how many faulty alleles must an individual have inherited from their parents? Two - one from their father, one from their mother 9 of 21 You only need one copy of the faulty allele to have Huntington's disease.
