Morgan coined the terms

Options

A. linkage and recombination
B. gene and allel
C. X body and linkage
D. homozygous and heterozyogus

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the terms coined by Morgan in genetics. It is important to identify the correct terms associated with his work.

2. **Identifying Morgan's Contributions:**
Morgan conducted experiments using Drosophila (fruit flies) to study inheritance patterns, particularly focusing on sex-linked traits. His work led to significant discoveries in genetics.

3. **Key Terms Coined by Morgan:**
- **Linkage:** Morgan introduced the term "linkage" to describe the physical association of genes located on the same chromosome. This means that certain genes tend to be inherited together because they are physically close to each other on a chromosome.
- **Recombination:** He also coined the term "recombination" to refer to the process by which genetic material is mixed during gamete formation, leading to new combinations of alleles that are different from the parental generation.

4. **Conclusion:**
Based on Morgan's research, the correct answer to the question is that he coined the terms "linkage" and "recombination."

5. **Final Answer:**
The terms coined by Morgan are "linkage" and "recombination."
