Detailed explanation-1: -During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents.
Detailed explanation-2: -Sexual reproduction allows for a greater genetic diversity through the process of Fertilisation. It involves the meiosis process which means a cell doubling its DNA, shuffling its genes and then dividing the shuffled DNA among four cells.
Detailed explanation-3: -Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.
Detailed explanation-4: -Sexual reproduction has the potential to generate new combinations of genes, unlike asexual reproduction, under which parents and offspring have identical genomes, barring mutational changes.
