Question

Which human disease is due to meiotic errors:

• A. Typhoid
• B. Messies
• C. Croles
• D. Down's syndrome

Answer 1

The correct option is D Down's syndrome

Down's syndrome is caused by meiotic errors. In individuals with Down's syndrome, an extra copy of chromosome 21 is present and hence it is called as trisomy-21. This happens due to defective meiosis of the cells where exact division of chromosomes into the cells do not occur.

Typhoid is caused by a bacteria, Salmonella typhi.

So the right answer is 'Down's syndrome'.
