Specific properties of bird karyotype described in the introductory section are a stimulus for cytogeneticists to search for other sources of information on chromosomes.
A perfected method of band analysis, based on the use of high resolution bands (HRT), is mainly applied in man in specialist medical studies (LEMIEUX et al., 1990).
This kind of research in birds has been sporadic (CARLENIUS et al.,1981; SASAKI, 1981).
A way to more thoroughly investigate the bird karyotype is to use meiotic chromosomes isolated
from male generative cells.
