Question

Quizplus · Accepted Answer

Testing the fertility of the offspring is the best choice to determine if the parents are the same species. If the offspring are infertile or have reduced fertility, it is an indication that the parents may not be the same species. This is because offspring from different species are often sterile or have impaired fertility due to differences in chromosome number or genetic makeup. Choices A and B may not be conclusive as some closely related species may have offspring with intermediate characteristics or resemble one parent more than the other.
