There is a group of invertebrate animals called rotifers, among which a particular group of species reproduces, as far as is known, only asexually. These rotifers, however, have survived a long evolutionary history without evidence of having been overcome by excessive mutations. Since the rotifers develop from eggs, but asexually, what can you predict?

E. No males can be found.

Explanation:

A. All males can produce eggs.

B. The eggs and the zygotes are all haploid.

C. While asexual, both males and females are found in nature.

D. The animals are all hermaphrodites.

E. No males can be found.

The existence of organisms of the same species as male or female (sexual dimorphism) is only necessary in sexually reproducing organisms.

In sexual reproduction, the sperm of the male fertilizes the egg of the female to produce a zygote.

Fertilization is not needed in organisms that reproduce asexually.

Therefore, for an organism that only reproduce asexually like the rotifers, one can easily predict that they do not exhibit sexual dimorphism and hence, no males can be found.

The correct option is E.
