An egg cell and a sperm cell

Detailed explanation-1: -Sexual reproduction takes two, a female and a male, each of whom contributes a gamete, the egg and the sperm, which unite to create a zygote containing the genetic information from both parents.
Detailed explanation-2: -The zygote’s genome is a combination of the DNA in each gamete, and contains all of the genetic information of a new individual organism. Zygote formation: egg cell after fertilization with a sperm. The male and female pronuclei are converging, but the genetic material is not yet united.
Detailed explanation-3: -These are two types of reproductive cells, or gametes. Each contains half of the genetic information necessary to form a complete organism. When an egg and a sperm fuse, they combine into a new cell called a zygote. The zygote contains all the genetic information it needs to become a new individual.
Detailed explanation-4: -Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.
Detailed explanation-5: -A zygote is the first diploid cell that is formed by the fusion of male and female gametes resulting in the formation of an embryo. The zygote stage development occurs in the first week of fertilization.
