Question

Saltation was proposed by

• A. Gregor Mendel
• B. Hugo de Vries
• C. J. B. S. Haldane
• D. H. J. Muller

Answer 1

The correct option is B Hugo de Vries

In the early 20th century, a mechanism of saltation was proposed as large mutations. It was seen as a much faster alternative to the Darwinian concept of a gradual process of small random variations being acted on by natural selection. It was popular with early geneticists such as Hugo de Vries, who believed that mutation caused species formation and hence known as saltation, i.e., single step large mutation.

So, the correct answer is option B.
