A group of individuals have lived for generations on an island. Their average height is 5 feet 2 inches. Eventually, ships stop by the islands bringing more fruits, vegetables and meats to their diet and more food overall. While the islanders continue to marry islanders and produce children, over generations the average height of the islander population reaches 5 feet 6 inches. What was most likely the main factor in this change?
19.
A female who is AO (iA, iO) mates with a male who is BO (iB, iO). What possible blood types can their children inherit
