Question

All of the following are the conditions under which Hardy-weinberg population exist except:
A. The population is extremely small.
B. Females choose mates based on a song preference.
C. There are no mutations occurring in the gene pool.
D. Members of the population do not migrate away to other locations.
E. The population is located on an island far from others and masses.

Answer 1

Hint: In a large, randomly mated population, the Hardy Weinberg rule asserts that genetic variances remain stable. If there are no disruptions such as mutation, migration, natural selection, etc., the frequency of alleles and genotypes remains constant from generation to generation, and the population is in genetic equilibrium. The Hardy Weinberg law is useful for analysing genetic variation in a population and comparing it to the calculated value from the Hardy Weinberg law if the population was in equilibrium.

Complete explanation:
Option A: Hardy-Weinberg equilibrium has a set of requirements that must be followed in order for the population's gene pool frequencies to remain constant. Random mating, no mutations, no migration, no natural selection, and a large sample size are all required. The population can expand or contract while the gene pool remains intact.
So, option A is correct.
Option B: Hardy Weinberg equilibrium is based on five assumptions: Mating at random. There are no mutations. There is no natural selection. There is no migration or gene flow. The population is enormous (no genetic drift).
So, option B is incorrect.
Option C: The Hardy-Weinberg principle asserts that a population is indefinite and unaffected by sexual, natural selection, mutation, or migration in a given population.
So, the option C is incorrect.
Option D: In order for the population's gene pool frequencies to remain constant, the Hardy-Weinberg equilibrium requires a set of requirements that must be met. Random mating, no mutations, migration, or natural selection are all required, as is a large sample size. While the gene pool remains intact, the population might grow or shrink.
So, option D is incorrect.
Option E: According to the Hardy-Weinberg principle, a population is indefinite and unaffected by sexual, natural selection, mutation, or migration.
So, option E is incorrect.

Therefore, Option A is the correct answet.

Note:
The Hardy-Weinberg principle asserts that a population is indefinite and unaffected by sexual, natural selection, mutation, or migration in a given population. The frequency of recessive genotypes can be used to compute the frequency of alleles. Then calculate the square root of this frequency to determine the recessive allele's frequency. The Hardy Weinberg equation is used to quantify the genetic variation in a genetically balanced population. For a gene regulated by two alleles, p is the frequency of dominant allele and q is the frequency of recessive allele in the Hardy Weinberg equation \[\left( {{p^2}{\text{ }} + {\text{ }}{q^2}{\text{ }} + {\text{ }}2pq{\text{ }} = {\text{ }}1} \right)\]. If allele frequencies are known, this equation may be used to calculate and estimate genotype frequencies, as well as to see if there is any variance between calculated and observed frequencies.
