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.
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.

Explain using one piece of information from the reading to support your choice. You should use those supports to back up your choice, that is, how did this piece of support lead you to your answer.arrow_forwardA population of 1,000 wild turkeys is studied and observed by scientists on an island. The scientists construct a study over five years to observe the temperature, amount of precipitation, daily value of berries individually consumed that were their exclusive food source, and available habitat for nesting. The scientist determined that as the climate changed, the population began to decrease. Using the Hardy-Weinberg Equilibrium as a null hypothesis, which of the following observations made by the scientists would support an associated alternative hypothesis? Due to the climate change, some birds may emigrate to a cooler location that would lead to a variation in the gene frequencies within the population. Variations in gene frequency due to advantages in natural selection would cause a greater number of males in the population to have more desirable traits. An increase in food consumption would cause the population to begin to exceed the carrying capacity that leads to a…arrow_forward
