amorphic allele - molecular evidence
Substantial deletion of Rif1 sequence, with a frameshift at amino acid 11.
2052bp deletion and 4 bp insertion (CCCG) in Rif1 that causes a frameshift at amino acid 11.
CCCG
fertile (with Rif11)
viable (with Rif11)
Rif11/Rif12 transheterozygotes exhibit a small but significant decrease in hatching rate.
