Question continuation;

..........type B. Type A is found to be more common in the mainland population from which the island was settled.

How could a geneticist best explain the dominance of blood type B in the island population?


Multiple choices;

A. Random mutations have occurred in the island population.

B. Genetic drift has reduced the frequency of type A individuals.

C. Natural selection has only occurred in the mainland population.

D. Environmental conditions on the island are less favorable for type B individuals.


Answer;

B. Genetic drift has reduced the frequency of type A individuals.


Explanation;

Which statement explains the difference between multiple alleles and polygenic inheritance?
sergeinik [125]

Answer:

B.  Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait.

Explanation:

  • Multiple alleles are an alternative form of allies and can occupy the same gene ad only two of them can be found in the same organism. Such as the ABO blood group.  
  • A polygenic or a multiple gene inheritance is a hypothetical gene that s often difficult to characterize and traits control a multiple of genetic loci, they are relatively small and interchangeable.
