ABSTRACT

Two types of B-chromosomes, a metacentric and a submetacentric, are recorded for the first time in Drosophila kikkawai collected from Bhubaneswar in India. Individuals with one or both types in different combinations were found in nature. Their relative frequencies in the mass culture laboratory stock were also determined.

Keywords: B-chromosomes; Drosophila kikkawai; burla.
