Which reproductive combination is most likely to produce hybrids in a hybrid zone?

• A. Two species with completely separate ranges
• B. Two individuals from the same species
• C. Two populations of the same species in different habitats
• D. Two different species with overlapping ranges

Answer: (D)

Verified step by step guidance

1. Understand the concept of a hybrid zone: A hybrid zone is a geographic area where two distinct species meet and interbreed, producing offspring of mixed ancestry, known as hybrids.
2. Consider the reproductive combinations: The problem presents different scenarios involving species and populations, and we need to determine which is most likely to produce hybrids.
3. Analyze the first option: Two species with completely separate ranges are unlikely to produce hybrids because they do not come into contact with each other.
4. Evaluate the second option: Two individuals from the same species will produce offspring of the same species, not hybrids, as hybrids are typically the result of interbreeding between different species.
5. Assess the correct option: Two different species with overlapping ranges are most likely to produce hybrids because they are in close proximity, allowing for interbreeding and the production of hybrid offspring.
