What is a PopG?

What is a PopG?

PopG is a very basic population genetics simulation program developed at the University of Washington. It is a stochastic simulation: if the fitness for Aa is 0.5, then each individual with genotype Aa has a 50% chance of survival. This means that sometimes a few more than 50% will survive, sometimes a few less.

How do I install PopG?

Installing PopG

  1. Click on the link.
  2. A downwards-pointing animated arrow in the lower-left portion of the browser window will move, pointing to a tab there called PopG. zip.
  3. PopG.
  4. Click (or if this does not work, double-click) on the PopG.
  5. Move that folder to where you want it to be.

What happens if a population is not in Hardy Weinberg equilibrium?

No natural selection. 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.

What are the 5 assumptions for Hardy-Weinberg?

The Hardy–Weinberg principle relies on a number of assumptions: (1) random mating (i.e, population structure is absent and matings occur in proportion to genotype frequencies), (2) the absence of natural selection, (3) a very large population size (i.e., genetic drift is negligible), (4) no gene flow or migration, (5) …

What are the 5 conditions of Hardy-Weinberg?

The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection. The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions.

What is Hardy-Weinberg used for?

Hardy-Weinberg Equilibrium (HWE) is used to estimate the number of homozygous and heterozygous variant carriers based on its allele frequency in populations that are not evolving.

What is the purpose of the Hardy-Weinberg principle?

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic variation of a population at equilibrium. In 1908, G. H. Hardy and Wilhelm Weinberg independently described a basic principle of population genetics, which is now named the Hardy-Weinberg equation.

How do you calculate Hardy-Weinberg?

The Hardy-Weinberg equation used to determine genotype frequencies is: p2 + 2pq + q2 = 1. Where ‘p2’ represents the frequency of the homozygous dominant genotype (AA), ‘2pq’ the frequency of the heterozygous genotype (Aa) and ‘q2’ the frequency of the homozygous recessive genotype (aa).

What are the 5 Hardy-Weinberg conditions?

There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene’s allele frequencies may change).

What are the 5 Hardy-Weinberg rules?

How is the Hardy-Weinberg formula useful for identifying evolution?

By describing specific ideal conditions under which a population would not evolve, the Hardy-Weinberg principle identifies variables that can influence evolution in real-world populations.
