RanGAPβTub85D.PK causes very strong segregation distortion in the presence of the "SD-5[R7]" chromosome (E(SD)1, Rspi, M(SD)1, St(SD)1) over a target homolog chromosome carrying Rspss. Segregation distortion does not occur if the target homolog chromosome carries Rspi in place of Rspss. Overexpression of RanGAPβTub85D.PK does not cause segregation distortion in the presence of the "SD-5[R16]" chromosome (which carries a strong suppressor of SD in addition to RanGAPSd, E(SD)1, Rspi, M(SD)1, St(SD)1) over a target homolog chromosome carrying Rspss. Segregation distortion can occur in the absence of RanGAPSd if flies are homozygous for E(SD)1 : Flies carrying chromosome SD-5[R7] (E(SD)1, Rspi M(SD)1 St(SD)1) / chromosome ReR-5 (E(SD)1 Rsps) exhibit moderate segregation distortion (k=0.74 +/-0.014) against ReR-5. This can be suppressed by the presence of RanβTub85D.PK or Rcc1βTub85D.PK. RanβTub85D.PK and Rcc1βTub85D.PK can both suppress the segregation distortion phenotype caused by RanGAPβTub85D.PK in the presence of the "SD-5[R7]" chromosome (E(SD)1, Rspi, M(SD)1, St(SD)1) over a target homolog chromosome carrying Rspss.

Segregation distortion is not seen RanGAPSd.tPa.1 flies in the presence of E(SD)1 or of the SD-5[R7] chromosome (E(SD)1, Rspi, M(SD)1, St(SD)1). RanGAPSd.tPa induces high levels of segregation distortion in the presence of the SD-5[R7] chromosome (E(SD)1, Rspi, M(SD)1, St(SD)1) over a target homolog chromosome carrying Rspss or Rsps.

M(Sd)1 enhances the activity of RanGapSD in an RanGapSD Rspss/RanGap+ Rspss male, and both homologues are distorted (rendered dysfunctional) in very high frequencies. Approximately 60-70% of the males are completely sterile.

Not the same as E(Sd).

M(Sd) is held in linkage disequilibrium with RanGapSD by inversions in many native SD chromosomes.
