Which type of linkage refers to genes that are located very close to each other on a chromosome?
Complete linkage
Incomplete linkage
Coupling linkage
Repulsion linkage
Complete linkage refers to genes that are located very close to each other on the same chromosome. When genes are in complete linkage, they are inherited together as a single unit and are rarely separated by recombination during the crossing over process that occurs during meiosis. This is because the physical distance between these genes on the chromosome is minimal, resulting in a low probability of genetic recombination events that would separate them. Thus, complete linkage is characterized by a strong association between the genes, and they are typically inherited as a linked group.
Option 1 is the correct answer.
