Chapter 6, Problem 1STP

Summary Introduction

Introduction:

The variety of genes within a species depicts the genetic diversity. A species contains many individuals that have their own genetic makeup. So, a species can have different populations, each having different genetic makeup.

Answer to Problem 1STP

Correct option is, option (A), The parrot population could have a greater resistance to disease than the hummingbird population.

Explanation of Solution

Explanation for correct options:

(A), The parrot population could have a greater resistance to disease than the hummingbird population. The importance of genetic diversity is to make the population resistant to any environment variation and diseases. Hence, option (A) is correct.

Explanation for incorrect options:

(B), Other parrot populations in different regions could become genetically similar to this one. In genetic diversity populations have different genetic makeup not the same. Hence, option (B) is incorrect.

(C), The parrot population could have a greater variety of abiotic factors with which to interact. Genetic diversity does not change the abiotic factors on which the organism depends to live. Hence, option (C) is incorrect

(D), The parrot population could interact with a greater variety of other populations. It is not necessary that parrot population will interact with more number of populations. Hence, option (D) is incorrect
