Almost like clones in their similarity to one

Almost like clones in their similarity to one another, the cheetah species’ homogeneity makes them especially vulnerable to disease.

In another perspective, the "clones" refers to the animal which is similar to one another. In order to agree to the comparison, the subject should be something sharing the same characteristic. "members" rather than species and homogeneity refer to animal base on the traits in the first clause.

Thanks for sharing your take on the question! :) I agree that in the first part of the sentence, we're referring to individuals of a certain group, in this case the cheetah species. For that reason, "members" rather than "species" or "homogeneity" is appropriate.

Almost like clones in their similarity to one another, the cheetah species' homogeneity makes them especially vulnerable to disease.

A. the cheetah species' homogeneity makes them especially vulnerable to disease
B. the cheetah species is especially vulnerable to disease because of its homogeneity
C. the homogeneity of the cheetah species makes it especially vulnerable to disease
D. homogeneity makes members of the cheetah species especially vulnerable to disease
E. members of the cheetah species are especially vulnerable to disease because of their homogeneity

We have a plural possessive pronoun "their similarity." The subject must therefore be plural. Only (E) gets this correct with "members."
