If you are a human geneticist looking for an ideal population in which to map disease genes,which of the following characteristics would help the mapping study?

B)all members of the population have the disease
C)large family sizes with poorly known genealogies
D)large family sizes with well-known genealogies

Mapping disease genes is easier when there are large family sizes with well-known genealogies, as this allows researchers to trace the inheritance patterns of the disease within the family and identify genetic markers that may be associated with the disease. Small family sizes or all members of the population having the disease may not provide sufficient genetic variation to be useful for mapping studies, and large family sizes with poorly known genealogies may make it difficult to trace inheritance patterns.
