Genetics have determined that the majority of individuals in an isolated island population have blood type B. Type A blood 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?

Genetic drift reduced the frequency of type A allele

Explanation:

Genetic drift can be defined as random fluctuations in the number and frequency of different gene variants (i.e., alleles) in a population due to random sampling. Genetic drift may be caused by founder effects when a small number of individuals becomes isolated from a larger population, thereby leading to the loss of genetic variation. In consequence, genetic drift is predicted to be strong on an isolated island population because the genetic pool of individuals living on the island is generally smaller in diversity compared to the original population due to random chance. In this case, it is expected that genetic drift reduces the frequency of type A individuals.

protein synthesis is an example of feedback mechanism which in homeostasis

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
