Answer: option B - some gametes may have an extra copy of some genes.
Explanation:
Actually, nondisjunction occurs in meiosis and results in FOUR ABNORMAL GAMETES/DAUGHTER CELLS: two gametes have an EXTRA copy of gene e.g XXY, while two other gametes LACK a required copy e.g XO
So, the right answer is some gametes may have an extra copy of some genes.

Explanation:
Because an unfertilized egg has half the chromosomes of a fertilized egg. The fertilized egg then splits, and continues splitting until the lizard is born. Always remember, whenever a question talking about an unfertilized egg, it has half the chromosomes of a fertilized egg. One more side note, it doesn’t matter what body part you talk about. A skin cell will have the same number, and identical chromosomes compared to a heart cell. (So long as it’s the same organism, if it isn’t, but part of the same species, it will have the same number of chromosomes, but it may have a unique set of chromosomes). If you want me to go into detail, I can, just respond to this answer.
