Abstract
A line of house flies carrying an autosomal translocation was maintained through 10 generations by mating translocation heterozygote males to non-translocated females, these 2 genotypes being recognized by marker genes. Selection was applied for enhanced egg hatchability and as a result, the mean increased by about 10%, but a plateau was reached beyond which there was no further response to selection. It is inferred that part of the response to selection was due to evolution of a small degree of non-random chromosome co-orientation in the translocation heterozygotes. The significance of such evolution to the use of translocations for pest control is discussed.Keywords
