WebDown syndrome (trisomy 21). Trisomy 18. Trisomy 13. Disorders affecting sex chromosomes (X and Y). An extra chromosome causes Down syndrome, trisomy 18 and trisomy 13. Screening for sex chromosomes can help predict the sex of the fetus and can also screen for differences in the usual number of sex chromosomes. Most organisms that reproduce sexually have pairs of chromosomes in each cell, with one chromosome inherited from each parent. In such organisms, a process called meiosis creates cells called gametes (eggs or sperm) that have only one set of chromosomes. The number of chromosomes is different for different species. Humans have 46 chromosomes (i.e. 23 pairs of chromosomes). Human gametes have only 23 chromosomes.
