Info

Accidents During Meiosis Can Result in a Trisomy or Monosomy Most abnormalities in numbers of autosomes are very serious or fatal. Down’s syndrome: Caused by a trisomy of chromosome number 21 (1 in 700 births). Mental retardation, mongoloid features, <strong>and</strong> heart defects. Most abnormalities of sex chromosomes do not affect survival. Klinefelter Syndrome: Males with an extra sex chromosome (XXY) (1 in 1000 male births). Turner Syndrome: Females missing one sex chromosome (XO) (1 in 2500 female births).
Down’s Syndrome is More Common in Children Born to Older Mothers
