Type A with no univalent, type B with autosomal univalents, type C with sex chromosome univalents, and type D with both sex chromosome and autosome univalents. Prominently, one of the two biggest chromosomes had a DAPI-bright indicuz at its end, while the other one had big DAPI-bright bodies in the middle region. From metaphase I to telophase I, all chromosome bivalents were positively stained with silver nitrate Figure 5g, h.

Seven genera and approximately 60 species occur worldwide, with three genera and approximately 20 species found in North America. Most testicular cells at leptotene-pachytene contained two nucleolar bodies, one with strong staining associated with the chromatin, and another one with less staining located far from the chromatin Figure 5d, e.

Due to this characteristic, if a chromosome is broken, the fragments are not lost and lethocwrus move to a pole at anaphase Hughes-Schrader and Schrader ; LaChance et al.

Meiosis in holocentric chromosomes: Then, distilled water was used to remove the coverslides and excess staining mixture. Bill Length Birds cm. These large, predatory, aquatic insects have the largest body size among the Indiccus. Instead, the occurrence of m-chromosome univalents was the result of desynapsis, not of asynapsis Nokkala and Nokkala Lethocerus Benacus griseus Say. Basal segment of beak longer than the second, less than 30 mm long See Figure 5below.


For standard staining, the fixed testes stained with lacto-acetic orcein were squashed on slides. Type A cells with no univalent were the typical chromosome pattern of testicular cells of L. Females of the giant water bug, Belostoma flumineum Hemiptera: In leptotene, the sex chromosomes appeared in one or two positively heteropycnotic letnocerus associated with the chromatin threads, while the nucleolus was less positively stained Figure 2b.
