WebFor instance, human somatic cells with chromosome numbers of (2n-1) = 45 (2n−1) = 45 or (2n + 1) = 47 (2n +1) = 47 are aneuploid. Similarly, a normal human egg or sperm has just one set of chromosomes ( n = 23 n = 23 ). An egg or sperm with (n-1) = 22 (n−1) = 22 or (n+1) = 24 (n +1) = 24 chromosomes is considered to be aneuploid.
