Chapter 22, Problem 1TYU

The largest unit within which gene flow can readily occur is a

1. A.    population.
2. B.     species.
3. C.     genus.
4. D.    hybrid.

Summary Introduction

Introduction:

Species is the particular group of organisms that share similar trait with each other and are able to produce viable offspring when they mate with each other.

Answer to Problem 1TYU

Correct answer:

The largest unit within which gene flow can readily occur is the species. Therefore, option (B) is correct.

Explanation of Solution

Reason for the correct statement:

Species is the highest group in which the production of viable offspring is possible that aids in gene flow.

Option (B) is given as “species”.

As “the largest unit within which gene flow can readily occur is the species” it is the right answer.

Hence, option (B) is correct.

Reason for the incorrect statement:

Option (A) is given as “population”.

Population involves the group of different genus that are not able to interbreed. So, it is a wrong answer.

Option (C) is given as “genus”.

Genus is the group of organism that share similar traits but might not be able to produce viable offsprings. So, it is a wrong answer.

Option (D) is given as “hybrid”.

Hybrid is the group of organism that shares the traits of two different species of the organism. So, it is a wrong answer.

Hence, options (A), (C), and (D) are incorrect.

Conclusion

The largest unit within which gene flow can readily occur is the species.
