FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Around a quarter of Gαounspecified/+ embryos show mild heart defects.
Gαounspecified has embryonic pericardial cell phenotype, enhanceable by +/Df(3R)mthl5-AD5
Gαounspecified has heart primordium | embryonic stage phenotype, enhanceable by Df(3R)mthl5-AD5/Df(3R)mthl5-AD5
Gαounspecified/+ ;Df(3R)mthl5-AD5/+ embryos show increases in the severity of heart defects (pericardial dissociation phenotype); double homozygotes show heart tube lumen abnormalities.
