PDF-CHROMOSOMAL POLYMORPHISMS OF CONSTITUTIVE HETEROCHROMA

Parallel examination of polytene and metaphase chromosome groups shows that inversion polymorphism in chromo some 3 of D reciicilia from East Maui Hawaii manifests a onetoone corre lation with a metaphase karyotype polymorphism due to the presence o.
