Abstract

Giemsa C-banded mitotic chromosome prepatations from White Leghorn, New Hampshire and Rhode Island Red inbred lines were compared for frequency of C-band regions on individual chromosomes. Except for autosomes 3, 6, 8 and 9 and W sex chromosomes, C-banding was extremely variable in other macrochromosomes. No divergence for C-band difference between homologous chromosomes of these lines was detected. Approximately 75% of the mitotic metaphase microchromosomes have recognizable C-band regions with the current technique.
