Detailed explanation-1: -Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
Detailed explanation-2: -Sexual reproduction also results in genetic variation among siblings. When a parent forms a gamete, only one chromosome from each homologous pair is included at random. So, an offspring might inherit a different combination of chromosomes (and alleles) compared to its siblings.
Detailed explanation-3: -Asexual reproduction generates offspring that are genetically identical to a single parent.
Detailed explanation-4: -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.
