Abstract Down syndrome‚ also known as trisomy 21‚ is the most common chromosome abnormality in humans and it occurs in all races. Approximately 1 of every 691 babies born in the United States each year is born with this genetic condition. Because people with Down syndrome have extra copies of genes on chromosome 21‚ the course of normal development is disrupted and this leads to the distinctive physical characteristics and other health issues that are associated with this syndrome. With appropriate

Genetic Project: Down Syndrome What is Down Syndrome? Down Syndrome is a chromosomal disorder where a child is born with an extra partial or full chromosome 21‚ thus leading to the over-expression of many genes present on this extra chromosome. Therefore‚ it is neither dominant nor recessive. Down Syndrome affects about 1 in 700 babies born‚ making it one of the most common genetic birth defects in the United States. There are actually 3 different types of Down Syndrome‚ Trisomy 21 (Nondisjunction)
