In the mid-1800s, an Austrian monk named Gregor Mendel Opens in modal popup window began his own experiments with plants. Unlike his predecessors, he used rigorous scientific methods in his experiments.

Mendel conducted his experiments with pea plants, which he grew in the garden of his monastery. The plants are easy to grow, reproduce quickly, and have several distinct characteristics Opens in modal popup window , or features, that are easy to observe. Characteristics of pea plants include flower color, seed color, and pea pod shape.

Moreover, Mendel knew that each characteristic exists as one of two traits Opens in modal popup window , or forms of the character. For example, the seed color characteristic exists as one of two traits: green or yellow.

Which of the following statements best describes a benefit of sexual reproduction?

Ivan

Among the listed options, we can conclude that option C which states that "It results in the diversity of the species that enhances the probability of survival." is correct.

Sexual reproduction offers organisms an advantage over those who undergo Asexual reproduction. Though there are benefits and drawbacks to each method, Sexual reproduction is a method that is better adapted to a changing environment and promotes the faster evolution of a species.

The main benefit of sexual reproduction is that it allows for a greater diversity of the species which enhances the probability of survival. This is due to the fact that sexual reproduction leads to varying combinations of alleles for specific traits, which coupled with selective reproduction (the ability of a member of the species to choose a spouse with desirable traits) leads to offspring who over time are increasingly better adapted to life in the given environment, with specific traits tailored for survival.
