    Answer:

    47 chromosomes

    Explanation:

    Meiosis is a kind of division that reduces the chromosome number of the daughter cells by half i.e. 2n – n. It occurs only in reproductive cells to produce sex cells or gametes. In humans, meiosis occurs to produce gametes (egg and sperm) that have 23 haploid chromosomes.

    N.B: Somatic human cells have 46 chromosomes

    According to this question, a meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm i.e. sperm with 23 chromosomes. A zygote that posseses (23 + 24) = 47 chromosomes will be produced.
