What is trisomy-21 klinefelter syndrome and turner syndrome?
All 3 conditions occur when non disjunction occurs in meiosis of the parent when they are producing gametes (egg or sperm). In normal meiosis, each parent gamete has 1 copy of each of the 22 somatic chromosomes and 1 sex chromosome. Non-disjunction occurs when 2 chromosomes go to one gamete and 0 go to the other.
Trisomy 21 (Down Syndrome) is when the zygote has 3 copies (instead of 2) of chromosome 21.
Klinefelter Syndrome (47 XXY) is when the zygote has 2 X chromosomes and one Y (a normal male is XY and a normal female is XX). Since they do have the Y chromosome, they are phenotypically (physically) male.
Turner syndrome (45 X) is when the zygote has only 1 sex chromosome (X chromosome). They are phenotypically male.
