Answer to Problem 1TY
The correct answer is option (d) evolution.
Explanation of Solution
Explanation/justification for the correct answer:
Option (d) evolution. A change in one or more heritable characteristics of population that occurs from one generation to the next is called evolution.evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.So, the correct answer is option (d).
Explanation for incorrect answer:
Option (a) Natural selection. natural selection is natural processwhereorganisms better adapted to their environment tends to survive and produce more offspring.so, this is an incorrect option.
Option (b) Sexual selection. Sexual selection is process where one organism member can choose mate of another sex. So, this is an incorrect answer.
Option (c) population genetics. Population genetics is branch of genetics where genetic varition occur within population.
Option (e) inheritance of acquired characteristics.when organism pass their traits to the offspring which is genetically acquired this is called inheritance of acquired characteristics.
