Like whippets, Thoroughbred horses have been intensely bred and selected primarily for speed by humans. Unlike whippets, Thoroughbred horses race shorter or longer races. The ability to successfully race a long distance is called "distance aptitude". Short races that have increased in popularity since the 19th century favor sprinters. A GWAS study found a g.66493737C>T SNP association with distance aptitude that had a p value of 1.02 x 10-10. In other words, the presence of a T SNP, rather than a C SNP, is associated with distance aptitude with a p value of 1.02 x 10-10. On average the optimum racing distance for C:C horses was 6.2 ± 0.8 furlongs, for C:T horses was 9.1 ± 2.4 furlongs and for T:T horses was 10.5 ± 2.7 furlongs. Furthermore, C:C horses have significantly greater muscle mass than T:T horses at two-years-old, indicating that the C SNP negatively affects myostatin. Which statement is correct regarding whether the g.66493737C>T SNP association with distance aptitude is significant or not in terms of the exact probability that the T:T SNP is associated with distance aptitude by coincidence, or random chance. Keep in mind that a p value of 0.05 means a 5% chance that two things are associated by coincidence or random chance. Select one: O a. There is a 1.02 x 10-8% probability that the T:T SNP is associated with distance aptitude by coincidence. This is much less than the maximum 5% probability (p=0.05) threshold needed for significance; therefore, this is significant. O b. There is a 1.02 x 10-8% probability that the C:C SNP is associated with distance aptitude by coincidence. This is much less than the maximum 5% probability (p=0.05) threshold needed for significance; therefore, this is significant. c. There is a 1.02 x 10-10% probability that the T:T SNP is associated with distance aptitude by coincidence. This is much less than the maximum 1% probability (p=0.01) threshold needed for significance; therefore, this is significant. O d. There is a 1.02 x 10-10% probability that the T:T SNP is associated with distance aptitude by coincidence. This is much less than the maximum 5% probability (p=0.05) threshold needed for significance; therefore, this is significant.
