  • Title: Genetic analysis by DNA fingerprinting in tsetse fly genomes.
    Author: Blanchetot A, Gooding RH.
    Journal: Insect Biochem Mol Biol; 1993 Dec; 23(8):937-44. PubMed ID: 8220390.
    Abstract:
    Genomic DNA from tsetse flies (Diptera: Glossinidae: Glossina Wiedemann) was analyzed by hybridization using the whole M13 phage as a probe to reveal DNA fingerprinting (DNAfp) profiles. Intrapopulation variability, measured by comparison of DNAfp profiles of tsetse flies from a large colony of G. brevipalpis, showed a high degree of polymorphism similar to that found in other animal species. Different lines of G. m. morsitans, G. m. centralis, G. m. submorsitans, G. p. palpalis and G. p. gambiensis established from small colonies displayed less genetic variability than the G. brevipalpis population. The analysis of pedigree relationships within an inbred line of G. m. centralis conformed to a Mendelian inheritance pattern. In the pedigree presented no mutations were observed, one fragment was linked to the X chromosome, and three fragment sets were linked, but most fragments showed independent segregation. M13 revealed no characteristic DNAfp profile differences between the subgenus Glossina and the subgenus Nemorhina, but a conserved distribution pattern was found in the laboratory colonies within each subspecies. M13 also revealed line specific DNA fragments that may be useful as genetic markers to expand the present linkage map of G. m. morsitans.
