What are the 5 assumptions of the Hardy-Weinberg equilibrium?

Which of the following is a Hardy-Weinberg assumption?

Possible Answers:

Gene flow between populations

Natural selection is in operation 

Correct answer:

Random mating

Explanation:

Random mating is one of the five Hardy-Weinberg assumptions that help maintain equilibrium. If random mating occurs, in tandem with the other assumptions, we can reasonably assume that there will not be a shift in allele frequencies or distributions.

The other Hardy-Weinberg assumptions are that natural selection does not occur, mutation does not occur, genetic drift (gene flow) does not occur, and that the population size is large.

Which of the following is not a Hardy-Weinberg assumption?

Possible Answers:

Mutation frequencies are high

Natural selection is not in operation

Correct answer:

Mutation frequencies are high

Explanation:

One of the five main assumptions is that mutations are negligible. This makes sense because, if a population is in Hardy-Weinberg equilibrium, evolution is not occurring. A low rate of mutations would help keep a population in equilibrium.

The five assumptions of Hardy-Weinberg equilibrium are a large population size, no natural selection, no mutation rate, no genetic drift, and random mating.

A population is in Hardy-Weinberg equilibrium. The gene of interest has two alleles, with 16% of the population portraying the features of the recessive phenotype. What percentage of the population is heterozygous?

The value of

gives us the frequency of the dominant allele, while the value of

gives us the frequency of the recessive allele. The second equation corresponds to genotypes.

is the homozygous dominant frequency,
What are the 5 assumptions of the Hardy-Weinberg equilibrium?
is the heterozygous frequency, and

is the homozygous recessive frequency.

16% of the population shows the recessive phenotype, and therefore must carry the homozygous recessive genotype. We can use this information to solve for the recessive allele frequency.

Correct answer:

Explanation:

The Hardy-Weinberg equations can be used to determine the expected frequency of genes and genotypes within a population, provided that only Mendelian segregation and recombination of alleles are at work. This is calculated mathematically using the equations:

We are told that 194 plants in a population of 200 demonstrate the dominant phenotype. This means that the sum of the homozygous dominant and heterozygous individuals is represented by the 194 plants described.

So, 97% of the plants show the dominant phenotype. This means that 3% must show the recessive phenotype.

Explanation:

The Hardy-Weinberg equations can be used to determine the expected frequency of genes and genotypes within a population, provided that only Mendelian segregation and recombination of alleles are at work. This is calculated mathematically using the equations:

In this example, the expected frequency to be solved for is the heterozygote GMGJ that is represented by the

Which of the following is not a Hardy-Weinberg assumption?

Possible Answers:

Population size is large enough to prevent random drift

There is no natural selection

There is nonrandom mating

Correct answer:

There is nonrandom mating

Explanation:

Random mating is a Hardy-Weinberg assumption, not nonrandom. The remaining answer choices are all standard assumptions for Hardy-Weinberg equilibrium. Nonrandom mating would allow certain alleles to be preferentially passed down over generations.
