Karyological study of four Indian birds

Abstract

SUMMARY -The chromosome complements of 4 species of Indian birds from Coraciiformes and Passeriformes orders are described. The meiotic chromosomes of the lone coraciiform species (new to cytology) have also been presented. Discussions have been made on the comparative karyology of congeneric and confamilial species and mode of karyotypic evolution, wherever possible, has been traced.

Karyological Studies on Six Species of Birds.

“…On the other hand, order Passeriformes has a diploid chromosome number ranges from 68 to 90, of which, the macrochromosomes range from 6 to 12 pairs while the microchromosomes from 26 to 37 pairs, Bhunya and Sultana (1979), Hobart et al (1981), Shields (1982), De Boer (1984, Mital and Sharma (1989), Bhunya and Das (1991) and Yaseen (1998). Order Strigiformes has diploid chromosome number ranges from 2n=66 to 2n=92, while order Gruiformes has diploid chromosome number ranges from 72 to 92, Belterman and De Boer (1984), Schmutz and Moker (1991) and Sasaki et al (1994).…”
