Solution

Type of sexual reproduction is Gamete formation.

Explanation:

Sexual reproduction is always accomplished with the assistance of two germ cells. Those two germ cells are female gametes and male gametes. Meiosis is the process by which gametes are formed. The number of chromosomes is reduced to half during meiosis, resulting in the formation of haploid gametes.
