Question

All cataracts were originally thought to be acquired; however, recent

research indicates that some cataracts are genetic in nature. What type of
study would be most likely to lend support to the claim that cataracts can
be inherited? *
A. analysis of cataract thickness in several species
B. studying age-related onset of cataracts within a species
C. linkage studies on DNA from families with a history of cataracts
D. comparing characteristics of cataracts caused by specific diseases

Answer 1

To determine if cataracts can be inherited, linkage studies on DNA from families with a history of cataracts provide the most evidence for genetic inheritance patterns by identifying genes that co-segregate with the condition.

Step-by-step explanation:

To support the claim that cataracts can be inherited, the most appropriate type of study would be C. linkage studies on DNA from families with a history of cataracts. These studies help to determine whether there is a genetic component to the condition by looking for genes or genetic markers that co-segregate with the disease within a family. It allows researchers to identify specific regions on chromosomes that may house genes responsible for the trait or condition in question. Hence, such a study would shed light on whether cataracts have a genetic inheritance pattern.
