What are the components of the Hardy Weinberg equation?

Contents

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 key components of the Hardy-Weinberg equilibrium?

Key points:

When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations. There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.

What is the Hardy-Weinberg equation and what do the element represent?

The Hardy-Weinberg Equation

p = the frequency of the dominant allele in a population. q = the frequency of the recessive allele in a population. 2pq = the frequency of the heterozygous dominant genotype. p2 = the frequency of homozygous dominant genotype.

What does the Hardy-Weinberg equation calculate?

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 assumptions of the Hardy-Weinberg principle?

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 factors affecting Hardy-Weinberg equilibrium?

The 5 factors are – gene flow, mutation, genetic drift, genetic recombination and natural selection.

What causes deviation from Hardy-Weinberg equilibrium?

Small Population Sizes: Genetic Drift

In a small population, the sampling of gametes and fertilization to create zygotes causes random error in allele frequencies. This results in a deviation from the Hardy-Weinberg Equilibrium. This deviation is larger at small sample sizes and smaller at large sample sizes.

What are the five factors that can lead to evolution?

Five different forces have influenced human evolution: natural selection, random genetic drift, mutation, population mating structure, and culture.

How does Hardy-Weinberg calculate allele frequencies?

To calculate the allelic frequencies we simply divide the number of S or F alleles by the total number of alleles: 94/128 = 0.734 = p = frequency of the S allele, and 34/128 = 0.266 = q = frequency of the F allele.

What does the Hardy-Weinberg principle predict?

The Hardy–Weinberg principle provides a mathematical model, which predicts that allele frequencies will not change from generation to generation. … where is the frequency of one (usually the dominant) allele and is the frequency of the other (usually recessive) allele of the gene.

What is homozygous condition?

​Homozygous

Homozygous is a genetic condition where an individual inherits the same alleles for a particular gene from both parents.
