I have sequenced roughly 24 genomes from two differentcontinents (Africa and South America), specifically for theenvelope gene of yellow fever virus. I used software to generatethe dN and dS ratio for each continent
Africa: (dS= 0.2065, dN= 0.0031.) dN/dS ratio= 0.0150
South America: (dS=0.5541, dN= 0.0112.) dN/dS ratio= 0.0202
Im unsure how to interpret these ratio's, and how the differencein the two suggests any differences in the type of selection forthe enveloped protein in each continent.
