Abstract:
By means of differential staining wiyh the Romanovsky-- Gimsa dye the distribution of G-bands was studied in chromosomes of bone marrow cells and of cultured peripheral blood lymphocytes in Papio hamadryas. All the homologous chromosome pairs were identified. It was shown, as compared Papio hamadryas karyotoypes with that of Macaca mulatta, that patterns of most chromosomes differentiation were similar. Certain differences between these species were observed in the character of differentiation of chromosomes 1 and 5 and also in parameters of chromosomes 2 and 21 (X).

Karyotyping
Describing the number and physical features of chromosomes can reveal abnormalities that underlie genetic diseases. This description is facilitated by special staining techniques that produce a particular banding pattern on each chromosome. State-of-the-art techniques make this approach even more powerful, enabling the detection of individual genes that cause disease.A Simple Chromosome Staining Technique Provides Valuable Scientific InsightSome genetic diseases can be detected by looking at...
Polytene Chromosomes
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also regularly...
