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.

Detailed explanation-2: -In sexual reproduction, two parents contribute genetic information to produce unique offspring. Sexual and asexual reproduction have advantages and disadvantages-which is why some organisms do both!

Detailed explanation-3: -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-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.

Detailed explanation-5: -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.
