What is Population Genetics?

64.5K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Distributions to Estimate Population Parameter

5.0K
The accurate values of population parameters such as population proportion, population mean, and population standard deviation (or variance) are usually unknown. These are fixed values that can only be estimated from the data collected from the samples. The estimates of each of these parameters are sample proportion, the sample mean, and sample standard deviation (or variance). To obtain the values of these sample statistics, data are required that have particular distribution and central...

Conservation of Small Populations02:04

Conservation of Small Populations

16.7K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

This protocol provides the steps from DNA extraction to experimental set-up for digital droplet PCR (ddPCR), including analysis for the identification and quantification of non-homologous end-joining (NHEJ) events at target sites following gRNA-induced Cas9 cleavage and DNA repair. Other uses of this method include applications such as polymorphism detection and gene-editing variant...

Area of Science:

  • Animal genetics
  • Quantitative genetics
  • Population genetics

Background:

  • Population management aims to maximize long-term breed competitiveness for consumer demand and conservation funding.
  • Breed competitiveness relies on genetic gain for total merit and sufficient genetic diversity.
  • Conservation value is enhanced by increasing a breed's contribution to the species' gene pool.

Purpose of the Study:

  • To review key genetic parameters essential for effective population management.
  • To compare methods for estimating these genetic parameters.
  • To clarify the application of these parameters in diverse breeding programs.

Main Methods:

  • Review of genetic parameters including kinships, native kinships, breeding values, Mendelian sampling variances, native contributions, and mutational effects.
  • Comparison of pedigree-based versus marker-based estimation methods.
  • Derivation of formulas for predicting future genetic parameter values.

Main Results:

  • Population management is transitioning from pedigree-based to marker-based estimates, enhancing accuracy and selection response.
  • Improved estimation of genetic parameters increases breed competitiveness and conservation value.
  • Auxiliary parameters like Mendelian sampling variances and native kinships refine management strategies.

Conclusions:

  • Optimizing genetic parameters is crucial for balancing breed competitiveness and conservation.
  • Marker-based estimates offer superior accuracy for population management.
  • Advanced genetic parameter utilization improves upon traditional recommendations for genetic population management.
