Answer
To facilitate variation in offspring, Sexual Reproduction arises as to the dominant reproductive type due to the combination of genetically diverse parents' contributions.
Explanation
Variation is a significant attribute of life. It stands out in reproduction by contributing to the aspect that helps species adapt to different environments, survive, evolve, and enhance diversity. Talking about the type of reproduction which gives rise to variation in offspring, explicit reference needs to be made about sexual reproduction. Biological diversity or variation comes primarily from genetically diverse parents in sexual reproduction. The reason is, sexual reproduction merges genetic material from two parent organisms. The mix of these genes creates offspring different from both parents. A zygote forms when the male sperm and female ovum combine; this results in genetic diversity due to the immense possibilities of gene combinations.Notably different from asexual reproduction that culminates in offspring exactly identical to the parent cell barring any possible mutations, sexual reproduction more often than not, gives rise to offspring genetically unique. They deem this process of mixing as recombination, or crossing-over, which typically transpires during the formation of gametes/sex cells i.e., sperm and eggs. Hence, voicing why sexual selection and comprehensive advanced evolutionary mechanisms that emphasize genetic diversity commonly occur among numerous species.
