Understanding hereditary disorders is necessary in order to fully and properly open a discussion on Down syndrome. A person’s traits begin with conception, and any conditions that pass on from parent to offspring is done through genes. There are 46 chromosomes, 23 from mom, and 23 from dad, in Down syndrome (which is also known as trisomy 21), there is an extra copy of chromosome 21 (Broderick, 2015). It is the most common chromosome disorder and genetic cause of mental retardation [ CITATION Fal13 \l 1033 ]. The mental retardation can be affected by educational interventions. Along with the mental retardation, children with Down syndrome tend to have very distinctive physical features. This would include poor muscle tone, heart problems, and flattening of some facial features (i.e.; the nose) (Broderick, 2015). It also should be noted that parents (mothers in particular), that are older tend to have a higher risk of having a child with Down Syndrome, it affects 1 in about 700 (Souroullas, 2013). Souroullas (2013), states that childhood death amung those with Downs Syndrome is in decline, and that it is evident that the disorder is closely associated with early discoveries of age related diseases such as premature menopause, or Alzheimers. It seems that there is a connection with accelerated ageing.
