“…Spontaneous asynapsis, on the contrary, must be due to causes other than divergence between homologous chromosomes, since it is known to be relatively frequent in highly inbred lines, such as for example the Oregon-R of D. melanogaster. It has been found, besides, that temperature has a pronounced influence on this kind of pairing, and that the more a chromosome is stretched (longer and thinner), the better it is paired (Beerman, 1962;Berendes, 1963;Perje, 1955). In addition, it can be altered by genetic causes (Gersch, 1959).…”

A new method for mapping gene differences between species is introduced. It is based on the asynapsis of homologous chromosomes in interspecific hybrids. Its validity has been investigated by comparing the pairing patterns of two Drosophila species and their hybrids, and by localizing on the chromosomes several diagnostic allozyme loci. The method can be used to map the genetic basis of any character exhibiting differences between species, although these species must fulfill some important conditions for the method to be applied with maximum efficiency.
