Detailed explanation-1: -The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes). The joining of haploid gametes to produce a diploid zygote is a common feature in the sexual reproduction of all organisms except bacteria.

Detailed explanation-2: -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-3: -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-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, also known as a fertilized ovum or fertilized egg, is the union of a sperm cell and an egg cell. The zygote begins as a single cell but divides rapidly in the days following fertilization. The zygote’s single cell contains all of the 46 necessary chromosomes, getting 23 from the sperm and 23 from the egg.
