Two theories which explain why the hypothesis was not accepted for in this study could be firstly that the study had too few individuals for significant results. There were no female mutants represented which made it impossible to see proper trends and analyse the data fairly. The second theory would   be that the TSHR sweep does not affect the behaviours that were tested. However the result from these tests does not confirm nor deny such statement. To conclude these tests would benefit from more individuals to be tested for stronger statistical results plus also to have all genotypes represented to fully investigate the affect the TSHR mutation have on domesticated chickens and potentially the domestication process in a range of species.
