BRAINCAKEThe Importance of Genetic Diversity
The difference between the DNA of individuals within a species is much less than the difference between DNA of different species.
All members of the species have the same genes but may have different versions of the same gene (alleles). The different alleles create genetic biodiversity within the species. The more alleles a species has, the more genetically biodiverse it is.
