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: -Sexual reproduction involves the fusion of male and female gametes whereas asexual reproduction does not require male and female individuals and no fusion of gametes takes place.
Detailed explanation-3: -Sexual reproduction is the creation of a new organism by combining the genetic material of two organisms. As both parents contribute half of the new organism’s genetic material, the offspring will have traits of both parents, but will not be exactly like either 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.
Detailed explanation-5: -Asexual reproduction generates offspring that are genetically identical to a single parent. 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!
