Amylase isozymes in the mosquito, Culex tritaeniorhynchus

A survey of laboratory stocks of Culex tritaeniorhynchus Giles has uncovered the presence of four electrophoretic variants and one apparent null allele of amylase. Linkage experiments with heterozygous males indicate that amylase is sex-linked. The gene sequence is w (white eye) - Amy (amylase) - M (sex), and the recombination frequencies are: w - Amy = 6.02%, Amy - M = 1.35% and w - M = 7.37%.
