How Adele Solomon can tell twins Jasmine and Teagan Masone apart Twins Teagan and Jasmine Masone with friend Adele Solomon. FRIENDS, teachers and even some family members can't tell identical twins Jasmine and Teagan Masone apart. No one, that is, except Adele Solomon, 14. Adele, who has Down syndrome, was in the same class as the twins when they started Reception, and they stayed together. While they share slightly different chromosomes and now go to different schools, nothing can separate the three best friends. Their friendship captures the spirit of today's World Down Syndrome Day, which aims to raise awareness about children living with the condition. It is caused by an extra copy of chromosome 21 in each of the body's cells. Soon after Adele was born, her parents John and Rosa Solomon started Foundation 21, a South Australian charity that helps fund speech therapy for about 70 children with Down syndrome. Today it is selling T-shirts with the slogan "Keep Calm It's Only an Extra Chromosome." "We want people to understand that our kids can do as much and achieve as much as any other child," Mr Solomon said.
