Palp-antenna, a homeotic mutant in Aedes aegypti.
Palp-antenna is a homeotic mutant of Aedes aegypti that modifies the apex of the maxillary palps of both sexes into a variable number of antenna-like segments. The fine structure of the antenna, including sexual dimorphism, is apparent in the mutant palps. Palp-antenna is a sex-linked recessive. a linkage distance of 27.9 +/- 0.45 crossover units from sex is estimated from F2 and backcross data. Penetrance is complete; expressively is variable. The fitness of the mutant compares favorably with that of the wild type. The mapping of the ppa locus lengthens the known chromosome 1 linkage map of Aedes aegypti.
