      Reference

      0.7% of heterozygous adults show at least one transformation phenotype. Hemizygotes are pupal lethal, homozygotes are larval lethal. trxM18/trxJY21 pharate adults sometimes develop small heads.

      Comments

      Partial complementation between hypomorphs produced phenotypes that were weaker than either of the hemizygous or homozygous phenotypes, either rescuing lethality or producing a weaker homeotic transformation phenotype. Transformations range from an average of 0.18 to 17.50 transformations/fly (males were scored for a possible 29 transformations, females were scored for a possible 26 transformations) in different allelic combinations.

      The following alleles form a series of progressively increasing penetrance and expressivity of phenotype when in transheterozygous combination with trx1 : trxM17 > trxZ32 > trxZ16 > trxZ11 > trxM18 = trxJY16 > trxE3.
