The constant dance of microevolution is driven by alleles, different versions of genes that determine traits. Sexual reproduction results in organisms inheriting a unique combination of genetic material from both parents, creating genetic diversity within a population. New alleles can appear through mutations or gene flow between populations.
The dance of alleles will continue, introducing new traits and variations in the ongoing story of evolution.
