Abstract
Frequencies of liver cytosolic aconitase (ACO1) allozyme phenotypes in female zebra finches (Poephilaguttata) conformed to a sex-chromosome-linked model of inheritance. Since birds are characterized by female heterogamety (ZZ males, ZW females), the observed absence of female heterozygotes for the cytosolic aconitase gene is interpreted as suggesting linkage of the ACO1 locus to the Z chromosome and hemizygous expression of this locus. Confirmation of this linkage assignment provides further support for the concept of evolutionary conservation of the avian Z chromosome.This publication has 3 references indexed in Scilit:
