Abstract
Ovaries from mature [female] larvae heterozygous for the X-chromosome mutants yellow and echinus were implanted into mature [female]larvae heterozygous for the Curly and Payne inversions (chromosomes II and III respectively). (These inversions cause a 285% increase in crossing-over between the yellow and echinus loci.) Crossing-over was measured in the implanted ovaries. A total of 403 offspring showed 3.7% of crossing-over. The control value (based on 5088 flies) was 3.3%. Comparison of the test and control cross-over values failed to show a significant difference (D = 0.4[plus or minus]Q3).This publication has 3 references indexed in Scilit:
