What is the primary reason the recessive gene frequency is significantly higher on the core islands compared to the mainland?
Answer
The islands functioned as semi-isolated environments allowing fixation within localized gene pools
The islands, being geographically separated, likely functioned as semi-isolated environments for long periods, allowing the recessive trait to become fixed within those localized gene pools at a much greater frequency than in the larger, more intermingling mainland black bear populations.
