| Abstract: | In a previous report (Palyga, J., Biochem.Genet. 29, 431-445, 1991), three subtypes oferythrocyte histone H1 were found to vary in a Japanesequail population. While H1.b and H1.z histones were eachrepresented by two electromorphs differing in apparentmolecular weights, a polymorphism of histone H1.a wasconnected with a lack of this protein in some birds. Asa genetic basis for this variability was demonstrated only in H1.b, here genetic data are providedwhich indicate that both H1.a and H1.z are encoded bytwo codominant alleles at a locus. A linkage analysis offamily data in 13 quail pedigrees has revealed a significant linkage between H1.a and H1.z andbetween H1.b and H1.z ( lod scores about 12 and 5,respectively). Thus, a gene for histone H1.z is locatedbetween H1.a and H1.b in the quail genome. |
