Answer :
The genetic variation seen in species as the result of selective breeding by process called sexual reproduction.
Gene variants, sometimes known as mutations, can cause genetic differences, or a normal process in which genetic information is rearranged as a cell prepares to divide can also cause genetic variations (known as genetic recombination). Different phenotypes can be introduced into an organism by genetic changes that change gene activity or protein function.
Choosing parents with specific traits to breed with one another in order to generate kids with more desired traits is known as selective breeding. For thousands of years, humans have carefully bred a variety of animals and plants, including crop species that produce more.
Natural selection is this process, and it is the primary driver behind evolution. Every living thing has a DNA molecule that holds its unique genetic information.
