Pooled whole genome resequencing to map autosomal barring in chicken

Domesticated chickens display a wide range of plumage variation. This study set out to map the loci responsible for autosomal barring using an informative backcross between Fayoumi and Light Brown Leghorn. Five Fayoumi females displaying autosomal barring were crossed with two Light Brown Leghorn males. Twelve of the F1 females were crossed with another Light Brown Leghorn. Four pools were constructed based on phenotype differences in the F2 progeny and were subjected to WGS to map the underlying genetic differences.
