Given that each body cell of a chimpanzee contains 48 chromosomes (2n = 48), we can determine the number of chromosomes in the gametes produced by this chimpanzee:
n = 2n / 2
n = 48 / 2
n = 24
Therefore, the gametes produced by this chimpanzee would normally contain 24 chromosomes (n = 24). This ensures that when two gametes combine during fertilization, the resulting offspring will have the diploid number of chromosomes (2n = 48), maintaining the species' genetic stability.
