Supporting Information

Summary

This animation series explores the biology of single nucleotide polymorphisms (SNPs), specific locations in the genome where single-nucleotide variations occur in many people. The series contains the following parts:

What Are SNPs introduces SNPs and where they are found in the genome.
Origins & Spread of SNPs explains how new SNP alleles arise through mutations and can spread through populations over generations.
SNP Population Patterns explores how scientists calculate SNP allele frequencies and why they might study patterns of allele frequencies across populations.

The animations may be viewed individually or as a complete series, depending on your class’s goals. Additional information can be found on this resource’s webpage.
