Questions and Answers

What is a gene pool?

  • The potential for change in a population due to environmental factors
  • The percentage of individuals with a specific genotype in a population
  • The ratio of any given allele in a population relative to all the other alleles of that gene at the same locus
  • The sum total of all the genes and their different alleles in a population at a given time (correct)

    • What does genetic equilibrium in a gene pool indicate?

  • The availability of the sum total of its alleles in a population
  • No change in the gene pool from one generation to another in the absence of disturbing factors (correct)
  • Continuous change in the gene pool from one generation to another
  • High frequency of a specific genotype in a population

    • What is allele frequency?

    Study Notes

    Gene Pool

    • A gene pool refers to the total collection of genes and their variations present within a particular population.
    • It encompasses all the alleles for every gene, contributing to the genetic diversity and adaptation of the species.

    Genetic Equilibrium

    • Genetic equilibrium occurs when the allele frequencies in a gene pool remain constant over generations.
    • It indicates that a population is not evolving, suggesting stable conditions without forces like mutation, selection, gene flow, or genetic drift acting on it.

    Allele Frequency

    • Allele frequency represents how often a specific allele appears within a gene pool, usually expressed as a fraction or percentage.
    • It is crucial for understanding genetic variation and predicting how traits may change over time in a population.

    Genotype Frequency

    • Genotype frequency refers to the proportion of different genotypes (combinations of alleles) present in a population.
    • It helps in studying genetic diversity and the inheritance of traits among different individuals in a species.

    Hardy-Weinberg Law

    • The Hardy-Weinberg Law was proposed by mathematicians G.H. Hardy and Wilhelm Weinberg in 1908.
    • It provides a mathematical model to study genetic variation in a population under certain conditions, supporting the idea of genetic equilibrium.
