Detailed explanation-1: -Each parent contributes a gamete-a sex cell that has half of the normal DNA of a regular body cell. In males, the gametes are sperm and in females, the gametes are eggs. When these two gamete combine during fertilization, the result is a zygote, which then continues to develop into an embryo.

Detailed explanation-2: -During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents.

Detailed explanation-3: -Sexual reproduction is a type of reproduction in which the genetic materials from two different cells combine, producing an offspring. The female sex cell, an egg, forms in an ovary.

Detailed explanation-4: -Two major types of sexual reproduction are syngamy and conjugation. Syngamy refers to the fusion of haploid sex cells resulting in the formation of a diploid zygote. Thus, in essence, syngamy refers to fertilization. It is the most common type of reproduction in multicellular sexual populations, including humans.

Detailed explanation-5: -Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell.
