Females hemizygous for fs(1)h6 that also carry Df(3R)red-P93 give rise to progeny with a high frequency of homeotic transformation of T3 to T2. Females heterozygous for fs(1)h6 that also carry Df(3R)red-P93 give rise to progeny with a low but significant frequency of homeotic transformation of T3 to T2.
Eggs are laid and defects are detectable prior to gastrulation.
Homozygous females lay eggs that fail to hatch.
temperature-sensitive
Relative strengths of the mutant alleles estimated as follows: Df(1)C128 = fs(1)h5 = fs(1)h4 > fs(1)h18 > fs(1)h3 > fs(1)h8 > fs(1)h17 > fs(1)h2 > fs(1)h6 > fs(1)h1.
Identification: Failure to complement the temperature sensitive sterility of fs(1)h1 or fs(1)h2. Relative strengths of the mutant alleles estimated as follows: fs(1)h2 > fs(1)h6 > fs(1)h1 for the temperature sensitive alleles, Df(1)C128 = fs(1)h5 = fs(1)h4 > fs(1)h18 > fs(1)h3 > fs(1)h8 > fs(1)h17 for the non-conditional alleles.
