Pedigree Chart Of Down Syndrome

Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. This extra genetic material leads to developmental delays and intellectual disabilities. Down syndrome is the most common chromosomal condition in humans, affecting approximately 1 in every 700 births. Individuals with Down syndrome typically have distinct physical features, such as almond-shaped eyes, a flat nasal bridge, and a protruding tongue.

A pedigree chart is a visual representation of a family’s genetic history. It shows how traits or disorders are passed down from one generation to the next. In the case of Down syndrome, a pedigree chart can help identify patterns of inheritance within a family. Each symbol on the chart represents a family member, with lines connecting individuals to show relationships. By examining a pedigree chart, genetic counselors and healthcare providers can better understand the risk of Down syndrome in future generations.
