The Y 6 Y 6 genotype has greater tumor growth and higher mortality than either Y 1 Y 1 and Y 1 Y 6 chickens. Y 6 Y 6 chickens also have a higher tumor profile index, an indication of a poorer response to Rous sarcomas compared to both Y 1 Y 1 and Y 1 Y 6 genotypes. Publications 1992-present Cotter, P.
