Offspring are the result of the fusion of the nuclei of dissimilar gametes.

|
|
Offspring produced will always be in a suitable environment

Detailed explanation-1: -Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition.
Detailed explanation-2: -The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring.
Detailed explanation-3: -Sexual reproduction happens via fertilization. Fertilization is the fusion of gametes from two parents. Fertilization leads to new, diploid offspring. Sexual reproduction results in genetic variation, or genetic differences, between parents and offspring.
Detailed explanation-4: -Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing over during meiosis, and random union of gametes during fertilization.
Detailed explanation-5: -About 1.3 billion years ago, sexual reproduction starts mixing genes and paves the way for the great diversity we see today. It’s hugely important on this timeline because it allows organisms to begin combing genes, allowing the next generation to do more than its parents; upping the chance of survival.
