Hardy-Weinberg Principle01:49

Hardy-Weinberg Principle

76.7K
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

15.8K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.3K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Genetic Variation01:25

Genetic Variation

1.5K
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles,...

Polygenic Traits01:18

Polygenic Traits

69.3K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Mutation, Gene Flow, and Genetic Drift01:09

Mutation, Gene Flow, and Genetic Drift

64.7K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Summary

Human height assortative mating was demonstrated in European-American and African-American populations. This non-random mating pattern influences genetic structure and requires further investigation in genetic association studies.

Area of Science:

  • Population genetics
  • Human evolutionary biology
  • Quantitative genetics

Background:

  • Human mating patterns significantly impact population genetic structure and genetic association studies.
  • Previous research on assortative mating primarily focused on phenotypic trait similarity, with limited quantification of genetic consequences.
  • The influence of non-random mating on genetic architecture remains incompletely understood.

Purpose of the Study:

  • To assess the degree of height-related assortative mating in European-American and African-American populations.
  • To quantify the genetic consequences of assortative mating using genetic variants.
  • To investigate the impact of assortative mating on genetic architecture.

Main Methods:

  • Studied genetic variants associated with human height.
  • Compared inbreeding coefficients estimated from height-associated variants versus random variants.
  • Analyzed data from European-American and African-American populations.

Main Results:

  • Significantly higher inbreeding coefficients were observed for height-associated variants compared to random variants.
  • Height-related assortative mating was demonstrated in both European-American and African-American populations.
  • P-values indicated statistical significance (P < 0.05).

Conclusions:

  • Height-related assortative mating is a significant factor influencing genetic structure in human populations.
  • Quantifying assortative mating through genetic variants provides insights into its genetic consequences.
  • Findings underscore the importance of considering mating patterns in genetic modeling and association studies.
