48

Explanation:
Detailed explanation-1: -Each of the eggs and sperm in the chimpanzee contains 24 chromosomes, and when fertilization occurs, the chromosomes unite to make a single cell with 48 chromosomes.
Detailed explanation-2: -While the genetic similarity between human and ape strengthened Darwin’s theory, a significant, unexplained discrepancy remained. While great apes all have 48 chromosomes (24 pairs), humans have only 46 (23 pairs).
Detailed explanation-3: -All chimpanzee gametes, which are the egg and sperm cells, are haploid. Cells that are haploid have half the total number of chromosomes. This means that the haploid number of chromosomes in a chimpanzee would be 24 because it is half of 48.
