Geneticist have determined that the majority of individuals in an isolate island population have blood type b. type a blood is f
ound to be more common in the mainland populations from which the island was settled. how would a geneticist explain the dominance of blood tpe b in the island population. 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.
B. Genetic drift has reduced the frequency of type A individuals,which <span>explains the dominance of blood type b in the island population.

The correct answer is genetic drift has minimized the frequency of type A individuals.
Usually, genetic drift takes place in small populations, where infrequently happening alleles encounter with a greater chance of getting lost. Once it starts, genetic drift will continue until the involved allele is the only allele present in a population at a specific locus or until the allele involved is lost.
In the given case, allele A is lost due to genetic drift phenomenon.
b. Cities like New York, New Orleans, and Miami will be flooded by ocean water.
Explanation:
The theory says global warming will cause the temperature of the planetary atmosphere to rise. The hotter environment will make ice masses of Greenland, and the poles to melt completely and make coastal cities like New York, New Orleans, and Miami flooded by the ocean.
<span>Bryophytes</span> are more adapted for moist environments. This is due to the fact that they can live in water-filled places with mild temperatures.
