  • a Dosage calculations assume that X-linked genes are fully dosage compensated in hybrid males. See Hmr1 retains ≥50% of the activity of Hmr+ in discussion for the estimation of Hmr+ dosage for the Hmr1 and In(1)AB rescue alleles.

  • b The order of genotypes listed within each viability class is not significant.

  • c Viabilities of genotypes in these classes were often highly variable. See references for details.
