Detailed explanation-1: -With sexual reproduction, offspring are genetically unique because they get a mix of genes from mom and dad. In sexual reproduction, the male and female reproductive cells are called gametes, or simply the sperm and egg. Each gamete contains half the number of chromosomes found in other cells of the organism.
Detailed explanation-2: -Sexual reproduction requires two parents. 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.
Detailed explanation-3: -In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.
