Detailed explanation-1: -This is because during sexual reproduction, the gametes of two parents, male and female, come together and fuse. Thus, the offspring has the genetic material of both the parents. Apart from this, variations are also introduced in the offsprings.
Detailed explanation-2: -In the process of sexual reproduction, haploid gametes produced by the meiotic division fuses to form a diploid zygote. A child inherits half of the genetic material from each parent. So, it may be they look alike but they are not identical to their parents.
Detailed explanation-3: -So in order to form a new organism, two gametes–the sex cells, sperm and egg–must fuse, further mixing the genes to produce more genetic diversity.
Detailed explanation-4: -Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique.
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!
