1938 Yearbk. Carnegie Inst. 37 305 Any dominant mutant which is lethal when homozygous and which shows pseudo-allelism to a dissimilar, non-allelomorphic but neighboring mutant is probably a deficiency.

1948 Genetics 33 113 Pseudo-allelism is characterized by the presence of closely linked genes, which seem to act developmentally like one.

1963 W. J. Burdette Methodol. in Basic Genetics 280 Pseudoallelism in Drosophila derives its genetic significance from the seemingly ambiguous observation that regular, reciprocal crossing over occurs between mutants presumed on phenotypic grounds to be allelic (and therefore occupying identical chromosomal sites).

1996 Hereditas 125 83 There were..5 probable cases of pseudoallelism in which some non-allelic lethal chromosomes were either semilethal or subvital in the heterozygous condition.
