Solution
Gene mutations, gene flow, genetic recombination, genetic drift, and chromosomal aberration are some factors or Causes responsible for genetic variation.
- Gene mutations: A sudden, permanent heritable change in DNA, such as a point mutation within a gene, leads to variations by altering the phenotype of an organism.
- Gene Flow: The movement of genes into or out of a population through migration, gametes, or DNA segments, which changes gene frequencies and contributes to genetic variation.
