Studies on the Effect of X Chromosome Inversions on Crossing over in the Third Chromosome of Drosophila Melanogaster.

Abstract

LL present theories of crossing over tacitly assume that events in one tetA rad (at least as far as crossing over is concerned) are independent of those occurring in the other tetrads of the cell. Yet as long ago as 1919 STURTEVANT suspected that the presence of a heterozygous inversion in one chromosome pair increases crossing over in a non-homologous pair… (More)
