antimorphic allele - genetic evidence
Polytene chromosomes normal.
lethal - all die during embryonic stage
some die during embryonic stage
When in combination with spl alleles of N alleles size of spl eyes slightly increases with no suppression of eye roughness.
Severe embryonic phenotype. Lethal when heterozygous with Dl9P, wings have irregular widening of all veins, vein 2 is broadened along entire length. Heterozygotes with Dlvi1 are lethal.
