Preliminary study on the karyotype of Ardea purpucea and Ardea cinerea, Ciconiifores

Abstract

The karyotype ofArdea purpucea andArdea cinerea, Ciconiifores, are presented in this paper. Chromosome preparations were made from bone marrow cells and stained with Giemsa. The diploid number of chromosome ofArdea purpucea andArdea cinerea are 62 ± and 60 ± respectively. The numbers of macrochromosome of these two birds are same, namely 11 pairs. Among them, six pairs of macrochromosome are morphologically very similar between the two birds.
