CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21. This extra genetic material causes the developmental changes and physical features of Down syndrome.

Detailed explanation-2: -The extra chromosome 21 leads to the physical features and developmental challenges that can occur among people with Down syndrome. Researchers know that Down syndrome is caused by an extra chromosome, but no one knows for sure why Down syndrome occurs or how many different factors play a role.

Detailed explanation-3: -An individual with Down syndrome inherits all or part of an extra copy of Chromosome 21. Symptoms associated with the syndrome include mental retardation, distinctive facial characteristics, and increased risk for heart defects and digestive problems, which can range from mild to severe.

Detailed explanation-4: -Down syndrome is a genetic disorder caused due to abnormal cell division. It is caused due to the presence of an extra chromosome 21 also known as trisomy of chromosome 21. It can be one extra chromosome 21 or a part of the extra chromosome present in all the cells or some cells.
