What does genetic linkage analysis aim to establish?

• A. Inheritance patterns of various disorders
• B. Location of genes responsible for specific disorders
• C. Inheritance of physical characteristics over generations
• D. Types of genetic markers in a population

Answer: (B)

Genetic linkage analysis is a method used to identify the location of genes associated with specific genetic disorders. This technique involves studying the inheritance patterns of genetic markers to find correlations between these markers and a particular trait or disorder. By doing so, researchers can narrow down the regions of the genome where the genes responsible for the disorder are likely to reside. This approach is particularly useful in complex disorders where multiple genes may be involved or when the specific genetic mutation is not yet known. While inheritance patterns of various disorders, physical characteristics, and types of genetic markers may be related topics within genetics, the core focus of genetic linkage analysis is specifically on pinpointing the genomic locations of genes involved in particular conditions. Thus, identifying the sites of these genes is key to understanding the genetic basis of the disorder and is a crucial step toward developing targeted treatment or preventative strategies.
