[The characteristics of the morphofunctional organization of the lampbrush chromosomes from the oocytes of the rock dove].

Nuclei and chromosomes isolated from growing oocytes of the pigeon C. livia have been studied by light microscope techniques. The pigeon chromosomes in diplotene assume a lampbrush form with a well expressed chromomere-loop organization.

[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.
