Chromosome Polymorphism in the European Hedgehog Erinaceus europaeus (Insectivora)

A karyotype study of chromosomes of two species of hedgehogs, Hemiechinus auritus and Paraechinus aethiopicus (insectivora: mammalia).

“…Such sub-acrocentrics were not observed in the karyotypes of H. auritus and P. aethiopicus. Furthermore, pair 21 in both E. e. europaeus and E. e. roumanicus was described to be acrocentric in nature (Geisler and Gropp 1967) but in the opinion of the present authors, this ap pears to be telocentric. However, in H. auritus and P. aethiopicus, no telocentric chromosomes appeared to occur.…”

“…In all the species of hedgehogs studied so far, except Erinaceus amurensis, the diploid chromosome number was confirmed as 48 (Geisler and Gropp 1967, Hsu and Benirschke 1968, Gropp et al 1969, Natarajan and Gropp 1971, Gropp and Natarajan 1972. In E. amurensis, the diploid number was reported to be 44 (Matthey 1973).…”

Variation in C-stained chromosome regions in European hedgehogs (Insectivora, Mammalia)

“…the Western European hedgehog (Erinaceus europaeus) and the Eastern European hedgehog (Erinaceus roumanicus). As pointed out by GEISLER and GROPP (1967) and KRAL (1967) both species have the same chromosome number, 2n = 48, but their karyotypes differ from each other, mainly in the distribution of large blocks of late replicating chromosome material (GROPP 1969).…”

Karyotype and Chiasma Frequency in the Indian Hedgehog,Hemiechinus Auritus Collaris

“…Excepting Erinaceus amurensis with 2n = 44 (KANG and KIM 1963 ), there occurs a common diploid number of 48 chromosomes in the various species of the genera Erinaceus and Hemiechinus of the family Erinaceidae, order Insectivora (PAINTER 1925;BovEY 1949a and1949b;SuiSSE 1956;JoRDON 1966;GEISLER and GROPP 1967;KRAL 1967a and1967b;BoRGAONKAR 1969;SHARMA et al 1971a and1971b). However, they depict certain taxonomical differences.…”
