Three Copies of Chromosome 21

Trisomy 21 is also known as Down Syndrome. People with this chromosomal anomaly have an extra copy of Chromosome 21. What this means is specific genes are overexpressed in their bodies. Today, people with Down Syndrome are more accepted in society compared to communities in the past. Some people have even become successful public figures! So, celebrate our differences with this trisomy-21 necklace. Buy it for yourself or give it as a gift. It would make a great present for doctors, geneticists, and people who are making the world a more accepting place for everyone.
