Imprecise excision of P{GawB}lov91Y resulting in deletion of 1.4 kb of sequence upstream of the original insertion (6.5 kb of P-element is retained), corresponding to intronic/flanking DNA not present in any final lov transcripts.
Approximate boundaries of a 1.4 kb deletion resulting from the imprecise excison of P{GawB}lov91Y. 6.5 kb of the P element remain.

Mutants are viable with normal external adult morphology.
Homozygous are hemizygous females are highly fertile in terms of eggs laid and egg hatch rate. However, the resulting larvae show delayed development and poor growth. Fewer individuals survive to adulthood and surviving adults are often reduced in size. lov47 larvae are also smaller than controls. From hatching onwards, lov47 larvae are sluggish, showing less than half the locomotor activity of controls. These larvae also show bouts of spontaneous backwards movements in the absence of obvious triggers. Feeding activity is also depressed. lov47 larvae show normal food sensing/preference.
lov47 adults show essentially wild type responses to light, attractive and repellent tastes, repellent odors and water.
lov47 homozygous and hemizygous adults that complete climb assays have slower climb rates. In addition, significant numbers of these flies fail to complete climb tests.
lov47 hemizygous adults show poor viability, typically dying within 5 days of eclosion.
lov47 homozygous and hemizygous males exhibit significantly lower courtship levels compared to controls. In addition, lov47 males show significant 'non-directed' courtship (i.e. while not pursuing the female); lov47 hemizygous males tend to be immobile in the presence of females and display 'passive' courtship only when females are very close. In the absence of females, both lov47 homozygous and hemizygous males are at least as active as controls.
lov38/lov47 male courtship is decreased and show non-directed elements (while not pursuing the female).
