Question

1) Define saltation and speciation?(class 12th biology)
​

Answer 1

Answer:

In biology, saltation (from Latin, saltus, "leap") is a sudden and large mutational change from one generation to the next, potentially causing single-step speciation. ... Speciation, such as by polyploidy in plants, can sometimes be achieved in a single and in evolutionary terms sudden step.

Answer 2

Explanation:

In biology, saltation (from Latin, saltus, "leap") is a sudden and large mutational change from one generation to the next, potentially causing single-step speciation. ... Speciation, such as by polyploidy in plants, can sometimes be achieved in a single and in evolutionary terms sudden step.

Saltation is single step large mutation that leads to the formation of new species (speciation).
