Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Population genetics?Early to mid-20th century
2. What is the discipline category?Subfield of Genetics and Evolutionary Biology
3. What is the primary applications?Understanding adaptation, speciation, conservation genetics, medical genetics, and evolutionary medicine
4. How do genes change over time?Genes can change because of new mutations, random chance, genes moving between groups, or because some genes help organisms survive better.
5. What is genetic drift?Genetic drift is when gene frequencies shift just by chance, especially in small groups. It can make rare genes more common or disappear.

Allele Frequency: The relative proportion of a specific allele within a population's gene pool.
Genetic Drift: Random fluctuations in allele frequencies due to chance events, more pronounced in small populations.
Hardy-Weinberg Principle: A null model stating allele and genotype frequencies remain constant in the absence of evolutionary influences.
Epistasis: The phenomenon where the effect of one gene is dependent on the presence of one or more other genes.
