Children with Down syndrome have an extra chromosome of the twenty-first pair. We all have twenty-three pairs of chromosomes, but these special individuals have three of the twenty-first chromosomes, instead of just two. This extra chromosome has often been referred to as the 'love chromosome' that, when planted in the child's DNA by God, brings a little bit of heaven's innocence to the earth through these special children.
Nino's "love chromosome" made him truly special.
