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).
The advantages of sexual reproduction are numerous. Several instances include:
more genetic variation
immunity against contagious diseases
fewer genetic diseases
Evolutionary fitness has increased
