Answer 1

the two main reasons for variation between organisms of the same species are

Inheritance and mutation

• Inheritance is the process by which genetic information is passed on from parents to child
• a mutation is a change in a genetic sequence. it includes changes in nucleotide base with another nucleotide base.

as in same species no of chromosomes are same but variation occurs in genetic sequence so variation occurs in organisms.
