Question
Using effect sizes in Table 1, calculate the polygenic score for Pat and Sal. Their genotypes are show below:
Pat: ne/ne Pk/pk Or6/Or6 Dn/dn Or3/Or3
Sal: Ne/ne pk/pk Or6/Or6 dn/dn or3/or3
People in the US eat more fruit than people in Australia. The GWAS identifies some genes underlying fruit consumption.
Which of the below are reasons we can't conclude that Australians are genetically inclined to eat less fruit (pick all that are
correct)?
The genetic basis of fruit consumption may differ between Australia and the US
Differences between the US and Australia may be environmental
These loci are not in Hardy-Weinberg proportions in Australia
The identified loci may not be causal for fruit consumption
The heritability of fruit consumption in the US is likely zero.
