Genetics of Esterases and 6-Phosphogluconate Dehydrogenase in Anopheles maculatus Complex.

摘要

Electromorphic variation for some esterases and 6-phosphogluconate dehydrogenase enzymes in Anopheles maculatus complex is controlled by four loci which are unlinked to sex. Esterase loci are linked to each other: Est-1-36%-Ext-4-16.5%-Est-3; but unlinked to Pgd-2. Linkage data were obtained by selfing the F1 generation from selected parents and analysing genotypes in the F2; the classical dihybrid-cross. Through indirect evidence, the enzyme loci are correlated to polytene chromosomes. The esterases probably lie on chromosome three (arms 3&4).
