title: Genetic variants of chicken erythrocyte histone H5.
abstract: Two allelic electromorphs a and b of chicken erythrocyte histone H5 have been detected in a sodium dodecyl sulfate polyacrylamide gel. In an acid-urea gel, however, each of the allelic variants was found to be accompanied by a slower migrating form. A comparison of alpha-chymotrypsin-digested products of H5.a and H5.b revealed that they differed in N-terminal domains. The H5 variants were distributed differently not only in various chicken races but also in distinct lines within a breed. Allele H5b was about 2.6-4.6 as abundant as its counterpart H5a in most chicken populations examined. These proportions were distorted in two Leghorn lines: the ratio of H5b to H5a was only 1.6 in line H22 and increased up to 32 in line G99.
