Final answer:
Yes, being able to interbreed and produce fertile offspring is a transitive relation in biology.
Step-by-step explanation:
Yes, being able to interbreed and produce fertile offspring is a transitive relation in biology. This means that if species A can interbreed with species B and produce fertile offspring, and species B can interbreed with species C and produce fertile offspring, then species A can also interbreed with species C and produce fertile offspring.
For example, consider the lion, tiger, and liger. Lions and tigers are two different species that can interbreed and produce fertile offspring called ligers. This demonstrates that interbreeding and producing fertile offspring is a transitive relationship in biology.
