Homozygotes show strong twisting of the bristles and have wavy hairs. snX2/snMR39B1 flies are sterile.
The reversion frequency of snMR39B1 is low in the absence of the MR chromosome, however when MRh12 is reintroduced, snMR39B1 becomes highly unstable and mutates to a weaker phenotype or wild-type at a frequency of 20.4 x 10-3.
