WebFeb 22, 2016 · The FM7c g haplotype on FM7a-23229 is unexpected, and suggests that this balancer is actually an FM7c that has been mislabeled as FM7a because of its sn + phenotype. Taken together, these results indicate that all chromosomes with large tracts of unique SNPs are FM7cs that lack the sn X2 allele. WebMay 5, 2007 · This FM7a balancer has an Hk + allele, because in female flies it does not produce a shaking phenotype in combination with either Hk 1 or Hk Y. FM7a was selected among all of the X chromosome balancers tested because it does not significantly affect daily sleep amount in an w 1118 background.
