This study was initiated to determine whether an allelic substitution of a dominant marker gene would identify a region close to a locus affecting expression in a metric trait. The rationale for the experiment was to utilize disequilibrium between a

Birds were brooded, reared, and laying house-tested at two widely separated sites: Animal Research Centre (ARC) and North Central Region Poultry Breeding Laboratory (NCRPBL). Two strain crosses and two control strains were represented at both sites,

AN air-comparison pycnometer was designed based on the concept originally developed by Day (1964) for measurement of volume of biological materials. The pycnometer was used to measure the volume of live quail. Details of the instrument and a calibrat
