Disturbed venation, a new sex-linked mutant, in the mosquito Aedes togoi.
Genetic linkage of a new sex-linked mutant, disturbed venation (dv), in Aedes (Finlaya) togoi has been studied by utilizing representative markers, s (straw-coloured larva), ru (ruby eye), and y (yellow larva), of the three linkage groups. The dv allele is recessive, disturbs drastically venation of the wing veins, cu1, m1+2, m3+4, r2, r3, and r4+5, and also affects shape of the wings along with loss of many fringe scales. The wings become shortened, especially in females, and somewhat narrowed in males. Much variation occurs in the expression of dv with its fairly good penetrance, although an increased mortality of the dv homozygotes may occur at pupal stage or during emergence. This allele was located at 5 to 6 recombination units from s and 28.56 units from sex locus (M) in the gene order of s-dv-M.
