Question

Saltation and Darwinian variations respectively are

• A. Large and small
• B. Directional and directionless
• C. Small and random
• D. Major variation and minor variation

Answer 1

Answer: (D)

Major variation and minor variation

Saltation is an abrupt variation in the appearance of an organism, species, etc, usually caused by a genetic mutation (single step large mutation).

Darwinian variations are that the speciation occurs gradually through a number of generations, with an accumulation of minor variations.

Mutations are random and directionless, while variations are small and directional as per Darwin.

So the answer is 'Major variation and minor variation'.
