Which statement is most supportive of the claim that genetic diversity is an advantage of sexual reproduction?(1 point)
Responses
Sexual reproduction creates genetic diversity, which results in a wide range of appearances in a population.

Given what you know about asexual and sexual reproduction, in three to five sentences, describe both types of reproduction:
Please describe at least 3 features of asexual reproduction
Please describe at least 3 features of sexual reproduction
Asexual reproduction is a type of reproduction that involves the production of offspring without the involvement of gametes or the fusion of genetic material from two parents. Three features of asexual reproduction include the production of genetically identical offspring, no need for a mate or fertilization, and the ability to reproduce rapidly. Examples of asexual reproduction include binary fission in bacteria, budding in yeast, and vegetative propagation in plants.
On the other hand, sexual reproduction involves the fusion of gametes from two parents, typically a male and a female, resulting in offspring with a unique combination of genes. Three features of sexual reproduction include genetic diversity in offspring, the need for a mate or fertilization, and the opportunity for genetic recombination through meiosis. Sexual reproduction allows for the exchange and reshuffling of genetic material, leading to increased variability within a population. It is observed in animals, plants, fungi, and some protists.
