Summary Introduction

To review:

The given blank space in the statement, “the ______ provides a simple mathematical model for a nonevolving population, also called a _______ population, in which ______ frequencies do not change over time. Are such a population likely to be found in nature? _______.”

Introduction:

A population comprises of all the species living in there natural habitat. Further species are able to interbreed with another in a population. Hardy Weinberg principle is also known as Hardy–Weinberg equilibrium and it states that the allele and the frequency of genotype present in the population will remain constant from one to another generation in the absence of evolutionary influences.

Explanation of Solution

Hardy–Weinberg equation describes a simple method to evaluate a non-evolving population via a mathematical formula. For this nonevolving population, it was assumed that the allelic frequencies to remain constant and thus the equality is termed as the equilibrium population. This consists of certain hypothetical conditions which are not likely to be seen in the real life.

This principle is a model, law, theorem, and it states that all the alleles present and even the frequencies of genotype present in one population will remain constant throughout the generations in the absence of other external evolutionary influences. Such population is not found, since every organism is constantly evolving as external evolutionary patterns like temperature, pressure, and climate plays a major role in adjustments and adaptations made by the organisms.

Conclusion

The hardy Weinberg principal provides a simple mathematical model for a nonevolving population, also called an equilibrium population, in which allele frequencies do not change over time. Are such a population likely to be found in nature? No.
