Happy-faced spiders (Theridion grallator) appear in four different forms, but they are still considered individuals of the same species. What could be the appropriate justification for this? A. All four different varieties can interbreed to produce a fertile offspring.. B. All four different varieties share a common habitat.. C. All four different varieties can interbreed to produce sterile offspring.
The correct answer is A. All four different varieties can interbreed to produce a fertile offspring.
As long as sexual reproduction provides the parents with fertile offspring, then the life forms belong to the same species. No matter what they look like or behave like, if they have regular healthy progeny, then they belong to the same species.
