Abstract
IT is one of the peculiarities of tetrasomic inheritance, such as we have been investigating for some years past1 in the purple loosestrife, Lythrum salicaria, that, for any two loci in homologous chromosomes, there are a large number of possible genotypes heterogenic at both loci, and therefore capable of throwing light on the process of genetic recombination. With only two alleles available at each locus, there are indeed nineteen such genotypes, and with the linked loci for short style and for pink, or rosy, flower colour, most of these have been obtained; although the six genotypes triplex for the dominant Short gene have been inaccessible, owing to the illegitimacy of Short by Short matings.
