TGG to TGA; revertant of AxsD; see GB:AF101361
Complete loss of the dominant phenotype: less than 2% X chromosome non-disjunction. Homozygotes show no meitoic phenotype, though transheterozygotes with Axsr2 show a strong meiotic phenotype. Effect is limited to homologous achiasmate segregations. Nondisjunction is not accompanied by a significant level of chromosome loss.
Revertant.
Does not suppress AxsD in transheterozygotes.
