Variations appear during meiosis due to:

Detailed Solution for Sample AFMC Biology Mock Test - Question 6

The appearance of new characters or traits in the progeny, compared with parents are called Variations.
These are due to the Independent assortment and Crossing over.

Independent assortment: When a cross is made between two individuals different from each other in two or more characters, then the inheritance of one character is independent of the inheritance of another character. It is called Law of independent assortment.

Crossing over: Exchange of chromatid segments between the non-sister chromatids of a bivalent is called crossing over.
