Heritability and number of genes controlling susceptibility of chick embryo chorioallantoic membranes (CAM) to RSV.
Two lines of commercial chickens differing significantly in pock responses on chorioallantoic membrane (CAM) of embryonating eggs were studied to estimate heritability and the number of pairs of genes which control this response. By using Wright's formula it was found that one pair of genes controls pock response of the CAM, suggesting a monogenic Mendelian inheritance of the trait. The heritability estimate of the trait was 0.71.
