what happens if the hardy weinberg equilibrium is violated?

If any one of these assumptions is not met, the population will not be in Hardy-Weinberg equilibrium. Instead, it may evolve: allele frequencies may change from one generation to the next. Allele and genotype frequencies within a single generation may also fail to satisfy the Hardy-Weinberg equation.

Hardy-Weinberg equilibrium assumes: no gene flow, mutation, genetic drift, or natural selection. "Fitness," in an evolutionary sense, refers to an individual's: reproductive success. ... genetic drift.

If either parent is ++, they can only have Rh positive children. If they're both +-, they have a 25% chance of an Rh negative child and a 75% chance of an Rh positive child. So, the most likely result of two A+ people reproducing is an A+ child.

If our statistical analysis shows that the significance level is below the cut-off value we have set (e.g., either 0.05 or 0.01), we reject the null hypothesis and accept the alternative hypothesis. ... You should note that you cannot accept the null hypothesis, but only find evidence against it.

If the P-value is less than (or equal to) , then the null hypothesis is rejected in favor of the alternative hypothesis. And, if the P-value is greater than , then the null hypothesis is not rejected. ... Using the sample data and assuming the null hypothesis is true, calculate the value of the test statistic.

Some of the major factors which affect the genetic equilibrium and induce the variability in population are as follows: (A) Mutations (B) Recombinations during Sexual Reproduction (C) Genetic Drift (D) Gene Migration (Gene Flow) (E) Natural Selection.

If the Delta G is positive, the reverse reaction (B ->A) is favored. If the Delta G is zero, there is no net change in A and B, as the system is at equilibrium. 3. The term "equilibrium" means that the relative amounts of A and B do not change in the reaction.

Explanation: When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. ... If crossing over did not occur until sometime during meiosis II, sister chromatids, which are identical, would be exchanging alleles.

The effective population size is the size of an ideal population (i.e., one that meets all the Hardy-Weinberg assumptions) that would lose heterozygosity at a rate equal to that of the observed population. ... Put differently, genetic drift is directly related to population size (small = more drift, large = less drift).

If Q is greater than K, the system will shift to the left. If Q is less than K, the system will shift to the right. If Q is equal to K than the system is already at equilibrium so it will not shift in either direction.

How would genetic variation be affected if, during meiosis I, maternal chromosomes always lined up together on one side of the metaphase plate and paternal chromosomes always lined up on the other side (ignoring the effects of crossing over)? ... One daughter cell would be 2n; the other would have no chromosomes.

For any given number of alleles, the expected heterozygosity is highest when the all the allele frequencies are equal. observed reslts indicate severe effects of small population sizes (population bottlenecks or metapopulation dynamics that severely reduced the level of genetic variation relative to that expected).

When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. ... It is obviously another source of genetic variation in offspring.

The Hardy-Weinberg model states that a population will remain at genetic equilibrium as long as five conditions are met: (1) No change in the DNA sequence, (2) No migration, (3) A very large population size, (4) Random mating, and (5) No natural selection.

Hardy-Weinberg equation. ... The equation is an expression of the principle known as Hardy-Weinberg equilibrium, which states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

The probability of committing a type II error is equal to one minus the power of the test, also known as beta. The power of the test could be increased by increasing the sample size, which decreases the risk of committing a type II error.

The Hardy-Weinberg Equation. For a population in genetic equilibrium: p + q = 1.0 (The sum of the frequencies of both alleles is 100%.) This page contains all the information you need to calculate allelic frequencies when there are two different alleles.
