通过对黑腹果蝇（Drosophila melanogaster）三龄幼虫觅食运动组成部分的一种自然多态性——漫游者/坐者（rover/sitter）的16个等基因亲本株系与坐者（sitter）亲本株系的反向杂交进行了遗传分析。来自男性和女性数据集的结果表明，漫游者/保姆的差异具有常染色体基础，漫游者完全优于保姆。y染色体、永久细胞质因子、瞬时母体因子及其相互作用对虎/母遗传无显著贡献。在女性数据中观察到轻微的x染色体效应。16个正交的雄性和雌性的Rover/sitter比率与假设单基因常染色体遗传的完全显性模型的结果没有显著差异。
The heredity of rover/sitter, a naturally occurring polymorphism in the locomotory component of Drosophila melanogaster third instar larval foraging behaviour was analysed by comparing 16 reciprocal crosses made using isogenic rover and sitter parental strains. Results from both male and female data sets indicated that rover/sitter differences have an autosomal basis, with rover showing complete dominance over sitter. The Y-chromosome, permanent cytoplasmic factors, transient maternal factors and interactions between them made no significant contributions to rover/sitter inheritance. A minor X-chromosome effect was observed in the female data. Rover/sitter ratios in both males and females of the 16 reciprocal crosses were not significantly different from those expected assuming a one gene, complete dominance model of autosomal inheritance.
