Question

Which of the following is not a character of class reptilia ?

• A. Body is covered by dry scales
• B. Each leg has five clawed digits
• C. Ventricle of heart is incompletely divided
• D. Skull bears two occipital condyles.

Answer 1

The correct option is D Skull bears two occipital condyles.

Repttiles have a body covered with dry scales made of keratin. They have a 3 chambered heart, with the ventricle incompletely divided, which helps prevent mixing of oxygenated and deoxygenated blood. The skull is monocondylic and bears a single occipital condyle.

So, the correct answer is 'Skull bears two occipital condyles'.
