Quantitative complementation tests.

Abstract

<p>Developmental time ratios for each line over a heterochronic mutant allele relative to that line over a <i>Canton S B</i> allele. The heterogeneity in the magnitude and direction of the DT ratios represents the genetic variation for each heterochronic gene. A) <i>invected</i>. B) <i>mastermind</i>. C) <i>cricklet</i>. D) <i>CG1491</i>. Blue bars represent larval developmental time and red bars refer to egg-to-adult developmental time.</p
