The correct Answer is:
To solve the question "When a cross is made between offspring and its parents, it is known as," we need to analyze the options provided and understand the definitions of different types of crosses in genetics. ### Step-by-Step Solution: 1. **Understand the Types of Crosses**: - **Monohybrid Cross**: This is a genetic cross that involves one pair of contrasting traits. For example, crossing a plant with purple flowers with a plant with white flowers. - **Dihybrid Cross**: This involves two pairs of contrasting traits. For example, crossing a plant with purple flowers and round seeds with a plant with white flowers and wrinkled seeds. - **Back Cross**: This is the cross between an offspring (F1 generation) and one of its parents. This is specifically what the question is asking about. - **Reciprocal Cross**: This involves crossing two organisms with reversed sexes to see if the sex of the parent affects the offspring's traits. 2. **Identify the Correct Answer**: - The question specifically asks about a cross between an offspring and its parents. The correct term for this is a **Back Cross**. 3. **Conclusion**: - Therefore, the answer to the question is that when a cross is made between offspring and its parents, it is known as a **Back Cross**. ### Final Answer: The correct answer is **Back Cross**. ---
