Final answer:
Down syndrome is a genetic disorder caused by an extra copy of chromosome 21, resulting in specific symptoms. Individuals with Down syndrome have unique strengths and talents alongside their challenges, so it is important to create a supportive environment.
Step-by-step explanation:
Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. It is also known as trisomy 21. Individuals with Down syndrome often have intellectual disability, vision problems, congenital heart disease, and a specific facial appearance.
For example, instead of the usual two copies of chromosome 21, individuals with Down syndrome have three copies. This additional genetic material affects the development of the body and brain, resulting in the characteristic symptoms of the condition.
While individuals with Down syndrome may face challenges, they also have unique strengths and talents. It is important to provide a supportive and inclusive environment to help them thrive.
