Phenotypic Description (Red Book; Lindsley and Zimm 1992)

l(2)56Fb

A single allele, which is lethal in homozygotes but produces an extreme Minute, semilethal phenotype in trans heterozygotes with Df(2R)017 and Df(2R)173. Complements all other l(2)56F mutants for viability; interacts with the the noncomplementing alleles of l(2)56Fa and M(2)56F to produce a Minute-like phenotype in the case of l(2)56Fa and an enhanced Minute phenotype in combination with M(2)56F. Trans heterozygotes of l(2)56Fb with the complementing alleles of the other two loci are wild type.

Expression Data

Testis-specificity index

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Other Comments

"Maps to the right of mus209" was stated as tentative. "Maps to the left of M(2)56F" was stated as tentative. One of a series of mostly recessive lethals recovered based on their lethality in combination with Df(2R)173 (cytology normal) and Df(2R)017 (Shellenbarger and Duttagupta, 1978; Duttagupta and Shellenbarger, 1980). Four complementation groups within Df(2R)017 but not Df(2R)173 (not further described) plus five sites uncovered by both deficiencies, which are separable by complementation analysis, but arbitrarily considered to represent three gene loci, two of which have complementing alleles, and the third of which interacts in trans with the other two. Except for the fact that mus209 maps to the left of M(2)56F and the inference that l(2)56Fb lies between them, nothing known of order of loci.
