Answer:
Two gametes are normal and two are abnormal.
Step-by-step explanation:
If sister chromatids did not separate from each other properly during meiosis II, the result of this cell division is the formation of two normal gametes and two abnormal gametes. The two normal gametes are produce with one copy of the chromosome each, whereas two abnormal gametes are formed in which one have two copies of chromosomes and the other have no chromosome.
