Abstract: | Summary The foot pad polytene chromosome IIIL ofParasarcophaga ruficornis andP. misera shows a heterozygous puff in the region 7B-C. InP. ruficornis the heterozygosity is manifested as a difference in the timing of puffing between the 2 homologues. The outer and inner dorsal cells of the same foot pad also reveal asynchrony in puffing at this locus.Acknowledgments. Thanks are due to Prof. U.S. Srivastava, Head, Dept. of Zoology, University of Allahabad for providing the laboratory facilities. |
