In essence, BMW is contending that truth should become the standard by which car buyers evaluate manufacturers' brand promises. A novel idea! And this idea has considerable merit, not just for automobile marketers. Companies often want to refine or even reposition their brand promise.
Down syndrome (DS) is a condition in which extra genetic material causes delays in the way a child develops, and often leads to mental retardation. It affects 1 in every 800 babies born. Autism is a complex developmental disorder that appears in the first 3 years of life, although it is sometimes diagnosed much later.
Down syndrome is a genetic disorder. Most people have 46 chromosomes in each cell. Children with Down syndrome have 47 chromosomes. They have an extra copy of chromosome 21. Normally, we inherit 23 chromosomes from our mother and 23 chromosomes from our father (for a total of 46). Babies with Down syndrome inherit an extra copy of chromosome 21 leading to 3 copies (one from Mom, one from Dad, plus one extra). We call this Trisomy 21.
