Chromosome homology in the climbing rats, genus tylomys (Rodentia: Cricetidae)

Chromosome C- and G-banding patterns in a bulgarian population of Microtus guentheri Danford & Alston (Microtinae, Rodentia)

“…Numerous investigations show that G, Q, or R-bands are conservative in related species. Harada (1978) maintained this for four species of bats: Sharma et al (1977) for two species of Rattus; Nadler et al (1977) in Ovis; Stock et al (1975) in Aves, Reptilia, Amphibia;De Vries et al (1975) for two species of Macaca; Mascarello et al (1974) for two species of Neotoma; Yosida et al (1973) for several more species of the genus Rattus; Pathak et al (1973) for Tylomys; Mori et al (1973) for three species of Rattus and so on.…”

A chromosomal banding study of three species of vespertilionid bats from Yugoslavia

“…Studies of chromosomes have led to a better understanding of systematic and phylogenetic relationships of bats and other groups (Baker, 1970;Capanna & Civitelli, 1973) but only a few studies have made use of banding techniques (Bickham, 1976;Mascarello et al, 1974;Pathak et al, 1973;Stock, 1975 …”

Chromosome banding pattern homology and its phylogenetic implications in the bat genera <i>Carollia</i>and <i>Choeroniscu</i><i>s</i>

“…One type of banding pattern (i.e., C or G) is not sufficient in most cases. Constitutive heterochro matin has been shown (Arrighi and Saunders, 1973) to contain repeated DNA sequences that have been "added on" to the genome (Pathak et al, 1973). It is unlikely that these sequences are transcribed in vivo, and they can, therefore, be disregarded in matching the G-band patterns of euchromatic segments.…”

“…Data derived from comparisons of banding patterns in related species of Rattus (Yosida and Sagai, 1972), Tylomys (Pathak et al, 1973), in related genera of primates (Stock and Hsu, 1973), and between rnuroid rodents belonging to different subfamilies (MASCARELLoet al, 1974) indicate that the organization of genetic material as reflected in the G-band pattern is very conservative. Barring extensive tandem fusions, as seen in Muntiacus (W urster and Atkin, 1972), or numerous paracentric inversions, the G-band pat tern can be recognized as more or less unchanged in related species, even between forms differing widely in karyotypic details.…”
