Two genetic loci are suspected of being in linkage disequilibrium. At the pitx gene two alleles are observed in a population, the most common (pitxi) with a frequency of 0.7. At the eda gene, two alleles are also observed, with the most common (edai) at a frequency of 0.58. Given the haplotype frequencies (below) are these loci in linkage disequilibrium in this population?
pitxi edai = 0.480
pitxi edaii = 0.260
pitxii edai = 0.120
pitxii edaii = 0.140
a) Yes, there is linkage disequilibrium.
b) No, there is no linkage disequilibrium.
c) Insufficient information to determine.
d) Linkage disequilibrium cannot be assessed from haplotype frequencies.
