Courtship defects in <i>lov³⁸</i> and <i>lov⁴⁷</i> males.

<p><b>A -</b> Directed courtship. Courtship indices for courtship directed towards the female. The courtship indices for <i>lov^91Y</i> in its original genetic background (91Y non-iso) and after isogenization of <i>lov^91Y</i> into the same <i>w⁺</i> background (see text) as the other <i>lov</i> mutants (91Y) are shown. Comparison of these two indices demonstrates that the new genetic background suppresses courtship significantly. Courtship behavior for <i>lov³⁸</i>, <i>lov⁴⁷</i> and <i>lov⁶⁶</i> is therefore compared only to the <i>lov^91Y</i> iso line (91Y) to correct for this background suppression of courtship. Statistics as previously. ** = p<0.01 as compared to isogenized <i>lov^91Y</i>. <b>B -</b> Non-directed courtship. Courtship indices for elements of the courtship ritual performed while not pursuing the female. Statistics as previously. *** = p<0.001 as compared to Canton-S control. <b>C -</b> Locomotor activity for males alone in courtship chambers (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0061270#s2" target="_blank">Material and Methods</a>). Control - Canton-S, 91Y = <i>lov^91Y</i>, 38 = <i>lov³⁸</i>, 47 = <i>lov⁴⁷</i>, 66 = <i>lov⁶⁶</i>,+ = <i>CyO</i> chromosome, def - <i>lov</i> deficiency chromosome <i>SB1</i>. Statistics as previously. ** = p<0.01 as compared to Canton-S control. ^## = p<0.01 as compared to isogenized <i>lov^91Y.</i>
