Question

David shows delayed intellectual development and has flattened facial features. The doctors explain that this genetic disorder is a result of extra genetic material in the 21st chromosome. Which disease is David suffering from?

Answer 1

David is likely suffering from Down Syndrome.

Answer 2

Down's syndrome

Step-by-step explanation:

Down's syndrome is caused by trisomy of chromosome 21. Trisomy refers to the presence of three copies of one chromosome in the genome. Since David has extra genetic material in chromosome 21, he is suffering from Down's syndrome.

Down's syndrome would affect the mental development and learning process of David. He is likely to have a broad skull with a small mouth.
