Most of the organisms considered to be “more advanced” from an evolutionary standpoint, reproduce sexually. This indicates there are advantages in sexual reproduction. What do you think the advantages are of sexual reproduction compared to asexual reproduction? Why do you think evolution favored sexual reproduction over asexual reproduction?

Expert Solution

Sexual reproduction is considered more advanced and useful from evolutionary aspect than asexual reproduction.

Sexual reproduction involves meiosis which produces variations because meiosis involves two genetic phenomenon viz crossing over and independent assortment of chromosmes hence genes. In crossing over there occurs reshuffling of genes between maternal and paternal chromosomes. This leads to production of new combination of alleles. Some paternal genes goes to maternal chromosome and vice versa. This leads to new combination of genes which produce variations.

Independent assortment allows maternal and paternal chromosomes to align independently of each other which also produces variations.

These variations are passed into offsprings and offsprings with variations are more sucessful to deal with environmental challenges and more capable to evolve and change according to the needs. Thus evolution favours organisms with sexual reproduction.

Most of the organisms considered to be “more advanced” from an evolutionary standpoint, reproduce sexually. This indicates there are advantages in sexual reproduction. Research the advantages of sexual reproduction compared to asexual reproduction and provide examples of both? What types of organisms mainly reproduce asexually vs those that mainly reproduce sexually? Why do you think evolution favored sexual reproduction over asexual reproduction? What is an example of an organism that can reproduce both ways? How is this advantageous? Make sure...

Dogs have 39 pairs of chromosomes and like all mammals are diploid organisms that reproduce sexually. All dogs belong to the same species but there are hundreds of different breeds (varieties or sub-species). Sexual reproduction offers advantages over simple binary fission at increasing genetic diversity in populations. Explain the role of meiosis in increasing genetic diversity
