•The file “Homework Data.xlsx†contains the results of a QTL analysis of stem rust severity (%) for wheat chromosome 3B. The analysis used homozygous inbred
lines from a resistant parent × susceptible parent cross, and a SNP-based chip for wheat. The mean disease severities for both parental genotypes at each of
200 marker locations, as well as the significance(-log10p-value) of the marker-phenotype associations, are provided.
•How many quantitative loci can be identified? What is their estimated location and effect size?
