Abstract
The diploid number of Hemidacthlus bawingii is 46 and the karyotype consists of 23 pairs telocentric chromosomes of various sizes, ranging from large to small sequentially. They show a gradual diminution in length, therefore, it is impossible to sort them into such distinct groups as large or small or micro-chromosomes. No heteromor-phic sex chromosomes is observed in the karyotype. A pair of Ag-NORs on the proximal region of No. 2 telocentric chro-mosme is found.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
