📖 1. Genetic Variations

🔑 Key Concepts & Definitions

• Genetic Diversity: The total number of genetic characteristics in the genetic makeup of a species, which provides the raw material for evolution and adaptation (see source content on variations).
• Mutations: Permanent alterations in the DNA sequence that can create new alleles; they are a primary source of genetic variation (no specific author/date provided).
• Allele Frequency: The relative proportion of an allele in a population, which can change over time due to genetic drift, selection, or mutation (see variations and heredity principles).
• Polymorphism: The occurrence of two or more different alleles at a locus within a population, contributing to genetic variation (no specific author/date provided).
• Genetic Drift: Random fluctuations in allele frequencies within a population, especially significant in small populations, leading to genetic variation (see source content on variations).
• Gene Flow: The transfer of genetic material between populations through migration, increasing genetic diversity across populations (see source content on variations).
