Chapter 17, Problem 5STP

Summary Introduction

Introduction:

According to the Hardy-Weinberg principle, a population in genetic equilibrium must meet five conditions: there must be no genetic drift, no gene flow, no mutation, mating must be random and there must be no natural selection. Violation of any of the five conditions, the population will not be in genetic equilibrium.

Answer to Problem 5STP

Correct answer:

The correct answer is option (C) A population of flowering plants always has the same group of natural predators.

Explanation of Solution

Explanation/justification for the correct answer :

Option (C). A population of flowering plants always has the same group of natural predators. The same group of natural predators may lead change in new population traits. Thus, this is the correct answer.

The explanation for the incorrect answer :

Option (A). A large population of deer inhabits a forest region. No change in population traits. Thus, this is an incorrect option.

Option (B). A particular population of flies mates randomly. New traits pass quickly to the rest of population Thus, this is an incorrect answer.

Option (D). A small population of birds colonizes a new island. Small population in an island does not violate genetic equilibrium. Thus, this is an incorrect answer.
