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;
-Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance.
-It occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Answer:
The correct answer is B. 1, 2, and 4
Explanation:
Option no 1 is true because before maturity, the mosquitoes will not be able to cause malaria and will be easier to kill.
Option no 2 is true because in order to ensure a safe control, the Brachiola gambiae shouldn't be dangerous to other animals or insects.
Option No 3 is not true because Mosquito larvae will contain the male larvae also. As the male larvae are not harmful, hence their growth shouldn't be stopped or they should not be killed.
Option No 4 is correct because before applying any controlling measures for a problem, it should always be kept in mind that it should not have negative effects on other food systems.
Answer No 5 is false because as the females Anopheles are harmful, they should be killed. The male Anopheles are not harmful hence, they should not be killed.
