Review:
Genetic Drift
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Genetic drift is a mechanism of evolution that occurs in populations due to random sampling of alleles.
Key Features
- Random changes in allele frequencies
- More pronounced in small populations
- Can lead to loss of genetic variation
Pros
- Contributes to genetic diversity
- Can lead to unique adaptations in isolated populations
Cons
- May result in loss of beneficial alleles
- Can increase genetic disorders in small populations
