Genetic linkage and linkage disequilibrium differ in that: a) Linkage describes

Question

Genetic linkage and linkage disequilibrium differ in that:

a) Linkage describes a situation in which a single gene performs multiple functions, whereas linkage disequilibrium occurs when two genes perform the same function.Linkage describes a situation in which a single gene performs multiple functions, whereas linkage disequilibrium occurs when two genes perform the same function.

b) Genetic linkage can be broken down by recombination, but linkage disequilibrium cannot.

c) Only linkage disequilibrium can be used to detect recent selective sweeps

d) Linkage disequilibrium changes slowly, while linkage changes quickly.

Explanation / Answer

c) only linkage disequilibrium can be used to detec recent sweeps.

linkage disequilibrium is the phenomenon of certain alleles of 2 or more genes to to be inherited together. One of the causes is genetic linkage - when 2 genes are placed closed to each other 9n the chromosome reducing the chances of a recombination event occuring between them. Other reasons behind linkage disequilibrium are mutations, selection, genetic drift, etc.
