The Pelobatids have a basal karyotype of 26 chromosomes, with 6 pairs of large and 7 of small chromosomes (6+7). From this karyotype, shown by Leptobrachium, Pelobates and Scaphiopus, those of Megophrys and Spea (5+8) may be derived, as well as that of L. pelodytoides, with only 24 chromosomes.

Abstract
The Pelobatids have a basal karyotype of 26 chromosomes, with 6 pairs of large and 7 of small chromosomes (6+7). From this karyotype, shown by Leptobrachium, Pelobates and Scaphiopus, those of Megophrys and Spea (5+8) may be derived, as well as that of L. pelodytoides, with only 24 chromosomes. Pelodytes has 24 chromosomes and a karyotype 7+5 differing from that of typical Pelobatids under several respects. © 1977 Birkhäuser Verlag.File in questo prodotto:
