      Detailed Description
      Statement
      Reference

      Complete loss of the dominant phenotype: less than 2% X chromosome non-disjunction. Homozygotes show exactly the same meiotic phenotype as AxsD/+, namely high levels of X and fourth chromosome non-disjunction. Effect is limited to homologous achiasmate segregations. Nondisjunction is not accompanied by a significant level of chromosome loss. Axsr2/+ ncd1/+ females show much higher levels of both X and fourth chromosomal nondisjunction than do either of the single heterozygotes.

      Does not suppress AxsD in transheterozygotes. There is no evidence for second site noncomplementation between Axsr2 and ald1.
