Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes is not altered.
Being genetically identical to the parent is advantageous for organisms when the environment changes fast, and reproduction is needed.
A gamete (a reproductive cell with one set of chromosomes, like an egg or sperm) combines with another to form a zygote, eventually developing into an organism of cells with two sets of chromosomes. Sexual reproduction is a type of reproduction that involves this complex life cycle (diploid).

more genetic variation
immunity against contagious diseases
fewer genetic diseases
Evolutionary fitness has increased
