Experimental alterations in the chromosome constitution of Sciara

Chromosoma Aims and scope Submit manuscript

Summary

Using two reciprocal translocations between chromosomes X and IV in S. coprophila it has been possible to derive two kinds of aneuploid females. Both of the aneuploid complements are detrimental — one is lethal, the other may give rise to viable, fertile adults. Males with aneuploid somatic complements have not been obtained; three different aneuploid complements were tested but gave negative results. Males with euploid soma and aneuploid germ line have been produced in three separate instances; they are viable and fertile.
