Question

Give any ‘two’ factors responsible for genetic variation.

Explain any two causes of genetic variation.

Answer 1

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.
