The effects of Minute loci and the possible involvement of transfer-RNA in sex chromosome non-disjunction in the Drosophila melanogaster male

Summary This report shows that certain Minutes can greatly increase the frequency of sex chromosome non-disjunction in the In(1) sc ^4L sc ^8R, ^5E y/y ⁺Y system in the Drosophila melanogaster male. This effect is evaluated and discussed with special reference to the recent finding that the Minutes may be deficiencies of transfer RNA loci.
