Summary The polymorphism of five enzyme loci (amylase, alkaline phosphatase, albumin, for 4‐week body weight was compared to that of the unselected control line (C). for 4 week body weight was compared to that of the unselected control line (C). Three loci in the C line and two in the P line demonstrated polymorphism. Plasma amylase was separated into six bands and zymograms were classified on the basis of these bands into nine phenotypes. Three of the nine types were of relatively high activity and six were of relatively low activity. All nine types were found in the C line, whereas, all birds of the P line had only the most active type. Two alkaline phosphatase alleles (Akp‐2 B and Akp‐2 C ) were segregating in the C line. Gene frequencies of alkaline phosphatase for the Akp‐2 B allele were 0.92 in the C line and 1.00 in the P line. Two albumin alleles (Alb Q1 and Alb Q2 ) were segregating in both populations. Gene frequencies for the Alb Q1 allele were 0.74 in the C line and 0.81 in the P line. Two red cell esterase‐D alleles (Es‐D F and Es‐D s ) were segregating in both populations. The gene frequency for the Es‐D s allele (0.61) was higher than that of the Es‐D F allele in the C line. In the P line the frequency of the Es‐D F allele was higher than that of the Es‐D s allele. Heterozygosities of the C and P lines were estimated as 0.2258 and 0.1560 respectively. The relative inbreeding coefficient of the P line, calculated from heterozygosities was 0.31.
