The correct Answer is:
To solve the question regarding linkage groups, let's analyze each statement step by step: 1. **Statement 1: Have genes which are linked in single chromosomes.** - This statement is **correct**. Linkage groups consist of genes that are located on the same chromosome. Since genes on a single chromosome are inherited together, they are considered linked. 2. **Statement 2: Show independent assortment.** - This statement is **incorrect**. Linkage groups do not show independent assortment because the genes that are linked on the same chromosome tend to be inherited together. Independent assortment occurs when genes are located on different chromosomes. 3. **Statement 3: Do not show independent assortment.** - This statement is **correct**. As mentioned, linked genes on the same chromosome do not assort independently during gamete formation. Therefore, this statement accurately describes linkage groups. 4. **Statement 4: In prokaryotes more than one.** - This statement is **incorrect**. Prokaryotes typically have a single circular chromosome, which means they do not have multiple chromosomes like eukaryotes. Therefore, linkage groups in prokaryotes cannot consist of more than one chromosome. ### Conclusion: The correct combinations regarding linkage groups are: - **Option 1**: Have genes which are linked in single chromosomes (Correct) - **Option 3**: Do not show independent assortment (Correct) ### Final Answer: The correct options are **1 and 3**.
