What type of reproductive life cycle is characterized by the steps shown below?

Diploid zygote -> Mitosis -> Diploid adult -> Meiosis -> Haploid sperm and eggs -> Fertilization -> Diploid zygote.

This is sexual reproductive lifecycle.

Explanation: There are basically two types of reproduction: sexual reproduction and asexual reproduction. In sexual reproduction, a diploid zygote is formed by the fusion of a haploid sperm and egg in the process called fertilization. The diploid zygote formed undergoes mitosis to form a diploid adult. Mitosis is a type of division in which a cell divides to produce two identical daughter cells each with the same number of chromosomes as the parent cell. This kind of cell division is necessary in growth and development. The diploid adult undergoes meiosis to produce haploid sperm and egg. Meiosis is a type of division in which a cell divides twice to produce four identical daughter cells each with half the number of chromosomes as the parent cell. Meiosis occurs only in the gametes. The haploid sperm and egg fuses in a process known as fertilization to form a diploid zygote.
