EQTL analysis for variation in reddish/brown colouration measured in growing feathers using gene expression levels obtained by Microarray

ABSTRACT: The aim of the experiment is to identify genes that are contributing too variation in the intensity of reddish/brown colouration seen in feathers from a wild x domestic advanced intercross line of chickens. RNA was isolated from growing feathers with varying levels of reddish/brown colouration (eg. dark red, red, orange, yellow). The intensity of the colour was measured relative to a true red colour chart and expressed as percentage of the reference colour. A lower colour score indicates a darker red colour(~0,30) and a pure white gives a score of ~0,95. QTL regions for the peak and average colour score measured across the wing were obtained from a mapping population. An eQTL analysis was performed by using the gene expression levels from all genes located within the previously identified
