Question

What is instantaneous speciation?

Answer 1

Speciation is a process by which one species give rise to two or more new species.

Explanation:

Instantantaneous speciation is a special type of sympatric speciation which occurs by polyploidy ( containing 3 or more sets of homologous chromosomes) .

This results in a new species being formed in one generation. It is the common origin of new species in plants. Many polyploids show increased vigour and have ability to cope better with extreme climatic conditions. Polyploids may multiply/reproduce only asexually.
