If nondisjunction (defect) occurs in Meiosis I (spermetogenesis or oogenesis) All sperms or eggs will be normal with half number chromosomes compared to the precursor cell All sperms and eggs will have either one more chromsome and one less chromosme and all will be abnormal Two sperm or egg cells will be normal and two cells abonormal in umber of chromosososmes All sperm or egg cells will have same number chromosomes as in precusor cells

Step 1
Nondisjunction is an error in cell division (meiosis) where chromosomes do not separate properly between the two cells. This can happen during Anaphase I, where homologous chromosomes fail to separate, or during Anaphase II, where sister chromatids fail to Show more…

During oogenesis, nondisjunction of X chromosome occurred in meiosis I. If the resulting egg unites with normal sperm, what genetic disorder(s) would be produced in live-birth offspring? Explain why?
Josee P.
If nondisjunction occurs during meiosis, only two gametes may form instead of four. Some gametes may have an extra copy of a chromosome. The gamete cannot join another to form an organism. The gametes redistribute chromosomes after meiosis.
Kerissa B.
A woman with normal chromosomes mates with a man who also has normal chromosomes. a. Suppose that, in the course of oogenesis, the woman's sex chromosomes undergo nondisjunction in meiosis I; the man's chromosomes separate normally. Give all possible combinations of sex chromosomes that this couple's children might inherit and the number of Barr bodies that you would expect to see in each of the cells of each child. b. What chromosome combinations and numbers of Barr bodies would you expect to see if the chromosomes separate normally in oogenesis, but nondisjunction of the sex chromosomes takes place in meiosis I of spermatogenesis?
