Summary Introduction

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.

Conclusion

Biological species involves organisms of the same species which can interbreed with each other.

n which situation would it make sense to use the morphological species concept?     When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed     When working with fossils from extinct organisms     When you only have genetic data about each organism in your study     When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive data
Which condition is the basis for a species to be reproductively isolated from other members? a. It does not share its habitat with related species. b. It does not exist out of a single habitat. c. It does not exchange genetic information with other species. d. It does not undergo evolutionary changes for a significant period of time.
a. What are the various types of reproductive isolating mechanisms that can lead to speciation? b. What are the different modes of speciation? c. Explain how evolution produce the tremendous amount of diversity among organisms.
