that individuals with Down Syndrome (caused by a triplet of genes at chromosome 21, Trisomy 4. It is seen 21) have a shortened life span. Some of this may be due to cardiovascular defects present in about 80% of individuals. A more modern theory is that the cell cycle of individuals with this condition is cycling faster than individuals without the condition. As such, Down Syndrome patients may have an accelerated epigenetic clock. Describe at least three biochemical/genetic/epigenetic factors that...

Please show calculation steps for this. Thank you Familial down syndrome is due to a Robesonian translocation that fuses chromosome 21 to chromosome 14 (most often). Individuals that have this translocated chromosome but no symptoms of Down syndrome are called translocation carriers. How many chromosomes do translocation carriers have (human diploid cells are typically 2N=46)? If an individual has a Down syndrome caused by the presence of this type of Robesonian translocation, how many chromosomes do they have?
