Transcribed Image Text:At locus A in mice, the frequency of the A1 allele is 0.3, and the frequency of
the A2 allele is 0.7.
At locus B, the frequency of the B1 allele is 0.1, and the frequency of the B2
allele is 0.9.
The frequency of all four possible gametes is as follows:
p(A1B1) = 0.03
p(A1B2) = 0.27
p(A2B1) = 0.07
p(A2B2) = 0.63
Which of the following statements correctly describes linkage equilibrium
or disequilibrium between the two loci?
a
b
Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer.
с
0.3
d
0.7
A₂
The frequencies of the four gametes add up to 1, so the two loci are in linkage equilibrium.
B₁
B₂
0.1 B₁
0.9
0.1
0.9
The frequency of B1 is independent of whether A1 or A2 is present in the gamete, so the two loci are in linkage
equilibrium.
The frequency of B1 is not equal to the frequency of A1, so the two loci are in linkage disequilibrium.
The frequencies of both A1 and B1 are not equal to 0.5, so the two loci are in linkage disequilibrium.
