Down syndrome is a condition in which a child is born with an extra copy of their 21st chromosome. This causes physical and mental developmental delays and disabilities. Use a medical genogram diagram to understand the down syndrome causes. As the hereditary medical genogram diagram suggests, both parents pass their genes on to their children. These genes are carried in chromosomes. When the child’s cells develop, each cell is supposed to receive 23 pairs of chromosomes, for 46 chromosomes in total. In children with down syndrome, one of the chromosomes doesn't separate properly. The children end up with three copies, or an extra partial copy, of chromosome 21, instead of two.
