Detailed explanation-1: -mutation. random mating between organisms. random fertilization. crossing over (or recombination) between chromatids of homologous chromosomes during meiosis. 08-Jun-2022
Detailed explanation-2: -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-3: -Sexual reproduction also results in genetic variation among siblings. When a parent forms a gamete, only one chromosome from each homologous pair is included at random. So, an offspring might inherit a different combination of chromosomes (and alleles) compared to its siblings.
Detailed explanation-4: -Final answer: Recombination is the most common mechanism of genetic variation in the population of sexually reproducing organisms.
