Concept explainers
The biological species concept is difficult or impossible apply to
- a. asexually reproducing organisms.
- b. large organisms.
- c. rapidly evolving organisms.
- d. plants.
Introduction:
Biological species concept involves interbreeding populations in the environment, which shows reproductive isolation from each other. Biological species do not involve exclusively asexual organism.
Answer to Problem 1MC
Correct answer:
The biological species concept is difficult to apply to asexually reproducing organism. Therefore, option (a). is correct.
Option (a). is given as “asexually reproducing organism”.
Explanation of Solution
Justify reason for the correct statement:
The biological species concept does not involve organism which reproduces asexually, as asexual reproduction does not provide species boundaries for sexual isolation.
Hence, option (a). is correct.
Justify reasons for the incorrect statements:
Option (b). is given as “large organism”.
Interbreeding does not occur in species which involves large organism and they are restricted to reproductive isolation. Hence, it is a wrong answer.
Option (c). is given as “rapidly evolving organism”.
In a species, identical population diverge and leads to the formation of new species by maintaining its reproductive isolation. Hence, it is a wrong answer.
Option (d). is given as “plants”.
Plants are sexually reproducing organism and they maintain their reproductive isolation. Hence, it is a wrong answer.
Hence, options (b), (c) and (d) are incorrect.
Biological species involves organisms of the same species which can interbreed with each other.
