Final answer:
Individual genetic maps are unique due to the genetic differences that exist between individuals of the same species. These differences are critical for creating genetic maps, which utilize genetic markers that show variability within a population.
Correct option is c) Variable
Step-by-step explanation:
Individual genetic maps in a given species are unique. This is because, although individuals of a given species are genetically similar, they are not genetically identical. Each individual has a distinctive set of genetic traits. The generation of genetic maps utilizes these minor differences in the genome between individuals in a population, which are useful for the purpose of genetic mapping. In general, a good genetic marker is a region on the chromosome that shows variability or polymorphism (multiple forms) in the population.
The use of genetic markers, which are regions of the genome with variations or polymorphisms, allows scientists to track and map the inheritance patterns of these markers within a population. This information is valuable for studying the genetic basis of traits, locating genes associated with diseases, and understanding genetic diversity within a species.
