What is the chromosome number in a human gamete with non-disjunction?A. 46B. 45C. 24D. 23

Non-disjunction is a process where chromosomes do not separate properly during cell division. This can result in gametes (sperm or egg cells) with an abnormal number of chromosomes.

In humans, a normal gamete should contain 23 chromosomes. However, if non-disjunction occurs, the gamete could end up with either an extra chromosome (24 in total - option C) or a missing chromosome (22 in total - not given in the options).

Therefore, the closest answer to the question would be option C. 24. However, it's important to note that non-disjunction can also result in a gamete with 22 chromosomes, which is not listed in the options.
