(c) Wrinkled tongue

(d) Straight tongue

The question was asked by my school teacher while I was bunking the class.

Query is from Inheritance and Variation Principles in division Principles of Inheritance and Variation of Biology – Class 12

Answer 1

The correct answer is (d) Straight tongue

To explain I would say: The tongue of the person suffering from Down’s syndrome is not straight. It is wrinkled and is comparatively bigger than a normal human tongue. The tongue is also furrowed. These features help in the diagnosis of Down’s syndrome.
