Detailed explanation-1: -One advantage of sexual reproduction is that it allows for genetic sameness.
Detailed explanation-2: -The advantages of sexual reproduction: it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease or change in environment is less likely to affect all the individuals in a population.
Detailed explanation-3: -The three main sources of genetic variation arising from sexual reproduction are: Crossing over (in prophase I) Random assortment of chromosomes (in metaphase I) Random fusion of gametes from different parents.
Detailed explanation-4: -Sexual reproduction results in genetic variation, or genetic differences, between parents and offspring. Offspring inherit one set of chromosomes from each parent. So, an offspring has a mixture of chromosomes (and alleles) from its two parents. Sexual reproduction also results in genetic variation among siblings.
