Two parents, who are thought to be different species, mate and produce viable hybrid offspring. When two of these hybrids mate, their offspring are not viable. What is the BEST interpretation of this data? A. The original parents are the same species because they can breed together. B. The original parents are the same species because they can breed together and produce viable offspring. C. The original parents are not the same species because they produce hybrids that impair the species’ development or survival in its environment. D. The original parents are not the same species because they produce hybrids that can have reduced viability and fertility when they mate.

Hybrids are offspring produced from the interbreeding of two species carrying recombinant traits from both parents. Depending on the genetic compatibility and relativeness, the hybrids are produced from two species. Hybrids may contain some traits as a result of recombination that are not present in both parents.
