Answer:
founder effect
Explanation:
When a few individuals from a population migrate to some new habitat and start a new population, the gene pool of the new population may not have the same allele frequencies as that of the original population. This change in the allele frequency of the new population is called the founder effect. In the given population, the increased frequency of the AB+ phenotype might have resulted from the founder effect. This is a chance event that occurs when a few individuals with a small fraction of genetic variations found a new population.

Thorndike's law of effect is described below.
Explanation:
- Operant Conditioning. A form of associative learning in which the consequences of a behavior change the probability of the behavior's occurance. According to Thorndike's Law of Effect. Behaviors followed by bad results are less likely to occur and behaviors followed by good results are more likely to occur again.
- The law of effect is a psychology principle advanced by Edward Thorndike in 1898 on the matter of behavioral conditioning (not then formulated as such) which states that "responses that produce a satisfying effect in a particular situation become more likely to occur again in that situation, and responses that produce
- Thorndike's Law of Effect states that a response followed by a pleasant consequence is more likely to be repeated, whereas a response followed by an unpleasant consequence is more likely to be diminished. ... This special stimulus has the effect of increasing the behavior occurring just before the reinforcer.
- Law of effect. Law of Effect. The law of effect states that if a response in the presence of a stimulus is followed by a satisfying event, the association between the stimulus and the response is strengthened.
