Scientists have thus called this gene tinmannamed after the Oz character of the same name. Does polyandry control population sex ratio via regulation of a selfish gene? For example, this technique showed that male courtship behavior is controlled by the brain.
The authors confirmed that this effect was not simply due to a higher death rate of SR sperm in storage by assaying sperm mortality rate. The number of offspring produced could not be normalized and was analyzed using a Wilcoxon rank test.
Biological Reviews of the Cambridge Philosophical Society 41 : — References 1. The answer may be that a system that actively facilitates the transition from sex signal assessment to maintenance regulation in XX cells, should also work to prevent mistakes in XY cells.
A number of studies have established that even moderate changes in RNA binding protein stoichiometry can have a large impact on target specificity, 53 therefore it is perhaps not surprising in retrospect to find that the subcellular distribution of Sxl protein is tightly regulated.
Thus, sex-combs appear to scale similar to sexually-selected signalling traits.
