Fig. 2. retn mutations affect viability. (A) Eclosion rates for
retn heteroallelic combinations.
retnz2-428/retndri2 (1) and
retnz2-428/retndri1 (2) offspring
eclose with 8% and 25% of expected rates;
retnRU50/retndri2 (3) and
retnRU50/retndri1 (4) eclose with 65%
and 68% of expected numbers;
retnz2-428/retndri8 (5) and
retnRU50/retndri8 (6) eclose with 71%
and 100% of expected numbers.
retnz2-428/retnRU50 (7) is completely
viable. (B) retn cDNA rescues partial lethality of
retn-Gal4/retnz2-428.
retn-Gal489/retnz2-428; +/+
trans-heterozygotes (1) eclose with 33% of expected numbers, while
retn-Gal489/retnz2-428;
UAS-retn/+ individuals (2) eclose at 100% of expected rates.
