Question

26 Example question In the plot below, the red lines show association between running speed and marker loci genotypes in mice, along 19 autosomes + X-chromosome. The dashed horizontal line is the threshold for significance. How many QTLs for running speed have been detected? Is there any evidence that the same genes might be affecting body size (blue lines) and running speed? xr why VA 16 17 18 19 X 1 2 3 4 5 6 712 8 9 10 11 Chromosome 12 13 14 15

Answer 1

6 loci have been detected with significant association with Running speed, 3 on Chromosome 10 and 3 o chromosome 12.

There is no evidence that the same genes might be affecting both Body size and running speed, as no QTL significantly associated with both, body size and running speed is found.
