Detailed Description

Statement

Reference

Mutant embryos derived from germline clones have holes in cuticle, are missing abdominal segments and have head involution defects. Germline clone females have 1-5% fourth chromosome non-disjunction. Escapers have many missing bristles, behavioural defects and wings held out perpendicular to the body.

Additional Comments

Genetic Interactions

Statement

Reference

Ova from neb^TE20/+ nod²/+ (or nod³/+ or nod⁴/+) transheterozygous females show a higher rate of 4th chromosome nondisjunction (up to 21%) than females heterozygous for either mutation alone.
