What is a gene pool?
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?
What does genetic equilibrium in a gene pool indicate?

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.
