Which statements describe the advantages of sexual reproduction? Check all that apply. results in no differences in DNA takes longer than asexual reproduction requires more energy than asexual reproduction takes less time than asexual reproduction results in DNA variations in the offspring can result in less competition for resources

Answered by admin @


Answer:

results in DNA variations in the offspring

Explanation:

Reproduction in living organisms can either occur sexually or asexually. Sexual reproduction requires two organisms of the same species to come together while asexual reproduction occurs with only an individual organism.

Based on the options provided in this question, sexual reproduction is of advantage over the asexual reproduction being that it produces offsprings with genetic variations. This is possible because during sexual reproduction, male and female organisms of the same species produce male and female gametes via meiosis respectively.

During meiosis, a unique phenomenon called CROSSING-OVER occurs in which the DNA in the gamete of each contributing parent is recombined. Hence, when the two gametes unite, the offsprings inherit a different combinations of genes (DNA) as the parents. This only occurs in sexual reproduction.

Genetic variation in offsprings of sexual reproduction is an advantage over the identical offsprings of asexual reproduction.
