Scientists look at how genes change in different groups of living things in a few ways:
Allele Frequencies: They check how often different versions of a gene, called alleles, show up in a group. They use a special formula called the Hardy-Weinberg equation to help with this: .
Genetic Markers: They use methods like SNP analysis to spot changes in certain genes.
Population Studies: By comparing different groups, scientists can see how genes move between populations and how traits change over time.
This genetic variation is super important for evolution and helps living things adapt to their environments!
