Final answer:
For a species with a haploid number of 23 chromosomes, there are over 8 million different combinations of maternal and paternal chromosomes possible for the gametes.
Step-by-step explanation:
The possible number of different combinations of maternal and paternal chromosomes in gametes is determined by the number of chromosomes in a haploid set. Since a species has a haploid number of 23 chromosomes, there are over 8 million possible combinations of maternal and paternal chromosomes (223).
