If a disease is co-inherited with a certain allele of a genetic marker in a pedigree, what does this suggest about the location of the disease gene with respect to the marker?
a) The locations are far apart.
b) The locations are the exact same.
c) The locations are likely close together on the same chromosome.
d) The locations are definitely on different chromosomes.
Does the blood cell from a patient with ‘universal donor’ bloodtype have greater or lesser number of protein moieties on its cell surface than a blood cell from an AB+ individual?
a) Lesser. Antibodies will not react with the foreign blood cells because there are no new shapes to bind onto.
b) Greater. More is better.
