WHITE EYE AND CURLED, RECESSIVE MUTANTS ON THE X CHROMOSOME OF ANOPHELES ALBIMANUS

Abstract

Two new mutants, white eye (we) and curled (cr), of Anopheles albimanus Wiedemann were isolated and studied. Both mutants are recessive and are approximately 18.9 ± 1.9 units apart on the X chromosome. White eye is fully viable, but cr is a recessive lethal. The mode of inheritance of these two mutants provides further evidence of an X-Y sex determination system in An. albimanus and a lack of homology between the X and Y chromosomes.
