24 (n+1)
Explanation:
Trisomy refers to the presence of one extra chromosome in the genome of the organism. This means that the affected individuals have a total of 47 chromosomes, instead of 46.
Nondisjunction during meiosis I or meiosis II produce the gametes with one extra chromosome. For example, nondisjunction in egg mother cell results in the production of some egg cells with "n+1; 24 chromosomes".
Fertilization of the egg cell carrying 24 chromosomes with a sperm carrying 23 chromosomes forms a trisomic zygote with 47 chromosomes.
