Gene migration or gene flow (1) involves the movement of genes between populations, affecting gene frequencies.
Genetic drift (2) refers to random changes in gene frequencies due to chance events, especially in small populations.
Mutation (3) introduces new genetic variations that can alter gene frequencies.
Genetic recombination (4) during gametogenesis creates new combinations of alleles, influencing genetic diversity.
Natural selection (5) acts on heritable traits, enhancing reproductive success and influencing the frequency of advantageous alleles in future generations.
All these factors contribute to changes in allele frequencies and can lead to speciation over time.

Factors Contributing to Speciation
Speciation occurs when populations of a species become genetically isolated and diverge into different species. Several key factors contribute to changes in gene and allele frequencies:
1. Gene Migration or Gene Flow
- This involves the transfer of alleles or genes between populations through migration.
- It maintains genetic diversity and can introduce new alleles, potentially leading to speciation if populations become isolated.
2. Genetic Drift
- A random process that can cause allele frequencies to change in small populations.
- Over time, genetic drift can lead to the fixation or loss of alleles, contributing to divergence between populations.
3. Mutation
- Mutations introduce new genetic variations into a population.
- These changes can create novel traits that may be subject to natural selection, potentially leading to the emergence of new species.
4. Genetic Recombination
- This occurs during sexual reproduction when genetic material is shuffled.
- It increases genetic diversity, which may enhance adaptability and speciation under changing environments.
5. Natural Selection
- The process where individuals with advantageous traits reproduce more successfully.
- Over time, natural selection can lead to adaptations that differentiate populations, fostering speciation.
Conclusion
All five factors—gene flow, genetic drift, mutation, genetic recombination, and natural selection—play essential roles in altering gene and allele frequencies. These mechanisms collectively contribute to the evolutionary processes that lead to speciation. Hence, the correct answer is option 'D'.
