Show Answer
Answer:
Correct Answer: A
Solution:
Option A) (i), (ii) and (iii) is correct. Hereβs an explanation:
(i) Adaptive ability is inherited: This statement refers to the inheritance of genetic traits that contribute to an organism’s ability to adapt to its environment. Traits that confer adaptive advantages are more likely to be passed down to offspring through genetic inheritance. Therefore, organisms can inherit the capacity to adapt, although the specific adaptations themselves are not directly inherited.
(ii) Adaptive ability has a genetic basis: This statement is correct. Many traits that contribute to an organism’s adaptive ability have a genetic basis. Genetic variation provides the raw material upon which natural selection acts, favoring traits that enhance survival and reproductive success in a given environment.
(iii) Fitness is the end result of the ability to adapt and get selected by nature: This statement is also correct. Fitness in evolutionary terms refers to an organism’s ability to survive and reproduce in its environment. Fitness results from adaptations that increase an organism’s chances of survival and reproduction, which are selected for by natural selection.
Therefore, option A includes all three correct statements about adaptation, genetic basis, and fitness, making it the correct choice.)
