✦ Synopsis

Two laboratory stocks of Anopheles minimus, each fixed for variant electromorphs of esterases, aspartate aminotransferase, hydroxyacid dehydrogenase, phosphogluconate dehydrogenase, mannose phosphate isomerase and glycerol dehydrogenase were used to assess linkage relationships between presumed gene loci controlling this variation. The two FI, which had been obtained from crossing the stocks, were backcrossed to a parental stock. Three loci controlled the esterases and one locus each of the other enzymes. Mpi is sex-linked. The rest are autosomal and suggested relationships are: Pgd 2.3% recombination from A at and unlinked to any other loci; Est-1 -33.8% -Est-3 -31.5% -Est-2 -21.0% -Had. Ged is unlinked to any other locus.

There was evidence of strong interaction between the X chromosome of one stock and autosomes of the other in which individuals bearing the X chromosome of the one suffered relatively greater mortality and had delayed development with respect to other genotypic classes.
