The birth of children with what chromosomal diseases is possible if meiosis is normal in the father, and the sex chromosomes in the mother do not diverge (both move to the same cell pole)? Or if the mother has meiosis normal, and the father has nondisjunction of the sex chromosomes?
If meiosis is normal in the father, and the sex chromosomes in the mother do not diverge, the birth of a daughter with X-chromosome polysomy syndrome (namely trisomy), a daughter with Shereshevsky-Turner syndrome, and a son with Kleinfelter syndrome is possible. Fetal death (with 44A + Y0 kit) in the third month of embryonic development due to the absence of the X chromosome is also possible.
If meiosis is normal in the mother, and the father has non-divergence of sex chromosomes, it is possible that a son with Kleinfelter’s syndrome and a daughter with Shereshevsky-Turner syndrome are born.
