Ribosomal RNA gene copy number and nucleolar-size polymorphisms within and among chicken lines selected for enhanced growth.

Poultry science - 1 Dec 1998

Su M H, Delany M E

Abstract excerpt

Ribosomal (r) DNA genotypes (rRNA gene copy number) and nucleolar phenotypes (nucleoli number and size) were studied in dam and sire commercial broiler pure lines from three primary breeder sources. Thirteen lines were studied to determine whether directionally selected broiler pure lines contain...
