Question

What is variation? Why it occurs?

Answer 1

Answer:

Polyploidy is a condition wherein organisms have three or more sets of genetic variation (3n or more). Crossing over (genetic recombination) and random segregation during meiosis can result in the production of new alleles or new combinations of alleles. Furthermore, random fertilization also contributes to variation.
