Which of the following is true about mutations?
A)While most mutations do not confer any advantage to a population,over time they provide for increased variability.
B)Modern medical technology has significantly reduced the number of new mutations in the human population.
C)Microevolution is the accumulation of mutations over time.
D)New mutations occur in order to increase the probability of a population surviving in a particular habitat.

Question

Quizplus · Accepted Answer

Most mutations do not confer any advantage to a population, but they can increase genetic variation within a population over time, which can be important for a population's ability to adapt to changing environments.

Answer: C
 Microevolution is the gradual accumulation of genetic changes, including mutations, within a population over time. This can lead to the development of new species or adaptation to changing environments.

Answer: D 
 This statement is incorrect. Mutations occur randomly and are not purposeful. While certain mutations may confer an advantage in a particular environment, they do not occur in order to increase the probability of a population's survival.

Answer: B 
 This statement is also incorrect. Modern medical technology has not significantly reduced the number of new mutations in the human population. While some medical treatments may reduce the harmful effects of certain mutations, they do not prevent them from occurring.
