In which of the following cases would asexual reproduction be most advantageous for an organism? a. when the need for adaptation is great b. living in a stable environment with little variation c. when new organisms are moving into and out of the population d. living where there are many available partners

The correct answer would be B. Living in a stable environment with little variation.

Asexual reproduction is a type of reproduction in which only a single organism or parent gives rise to the offspring. It is usually practiced by single-celled organisms such as bacteria, archaea et cetera. Sometimes, plants and fungi also reproduce asexually.

It does not include meiosis and fusion of gametes. Thus, the offspring produced are exactly the same as the parent and are called clone. In addition, they also lack genetic variation in a population due to the absence of meiosis and fertilization.

Thus, asexually reproducing organisms can survive best in a stable environment which shows little or no variation.

the answer is trees if i'm not mistaken
