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

Cytological studies of certain desert mammals of Saudi Arabia 3. The karyotype of Paraechinus aethiopicus.

“…The validity of our finding is closely checked by comparing the results of the karyotype of Hemiechinus auritus reported by Bhatnagar and El-Azawi (1978) with the observation of Sharma et al (1975) on the karyotype of the same species. Al though the method of Levan et al (1964) has been used by these different authors for the classification of the chromosomes, there is a clear contradiction with regard to the telocentric chromosomes.…”

“…Although the previous report of Paraechinus aethiopicus is in general agreement, minor differences do exist in the present karyotype. Bhatnagar and El-Azawi (1978) state the karyo type consists of 17 pairs of metacentric, 6 pairs of submetacentric autosomes, a me dium sized metacentric X chromosome and medium sized submetacentric Y chro mosome. The present study classifies the autosomes as 14 pairs of metacentric, 9 pairs of submetacentric chromosomes, a medium sized metacentric X chromosome and a small metacentric Y chromosome.…”

“…Thus we consider that misnomenclature of autosomal chromosomes as reported by Bhatnagar and El-Azawi (1978) may be a matter of erroneous calculation in the measurements of the chromosomes , but their classification of the sex chromosome (Y) has no strong basis. An explanation for this discrepancy may be that intraspecific Y chromosome polymorphism exists in the Aethiopian hedgehog as has been described in Syrian hamsters (Lehman et al 1963) and in some strains of laboratory rats (Hungerford and Nowell 1963 …”

“…To the best of our knowledge there is only one report about the karyotype fo Paraechinus aethiopicus from Iraq (Bhatnagar and El-Azawi 1978).…”

“…On the other hand, karyology of E. concolor was studied from former Czechoslovakia (Král, 1967), Austria (Geisler and Gropp, 1967; Gropp et al., 1969), Russia (Orlov, 1969), North Africa (Gropp and Natarajan, 1972) Bulgaria (Markov and Dobrijanov, 1974), former Yugoslavia (Đulič and Tvrtković, 1979), Greece (Giagia and Ondrias, 1980), former Yugoslavia (Kryštufek, 1983); Europe and Russia (Zima and Král, 1984), Jordan (Qumsiyeh, 1991) and Turkey (Doğramacı and Gündüz, 1993); H. auritus from Afghanistan (Gropp et al., 1969), Daghestan (Orlov, 1969), Iraq (Bhatnagar and el‐Azawi, 1978), India (Sobti and Gill, 1980), Egypt (De Hondt, 1988), Ukraine (Zagorodnyuk and Mishta, 1995) and Turkey (Kefelioğlu, 1997; Çolak et al., 1998).…”
