[Molecular and cytologic analysis of clusters of moderate repeats of bird genomes].
Pigeon genome long sequences containing clusters of moderately repeating elements have been cloned. Molecular analysis has shown a dispersed distribution of the repeats in both pigeon and chicken genomes. Within a single cluster, a scrambled distribution of elements belonging to different families of repeats has been shown. Similar repeated sequences have been revealed within clusters. The analysed clusters of repeats are characterized by a limited structural variability in the genomes. In situ hybridization revealed the localization of sequences complementary to the cloned clusters in pigeon and chicken macrochromosomes. Preferential localization has been demonstrated in telomeric and centromeric chromosome regions as well as in the region of R-bands.
