Virility Deficiency and the Sex-Ratio Trait in DROSOPHILA PSEUDOOBSCURA. I. Sperm Displacement and Sexual Selection.
The Sex-Ratio (SR) phenomenon is associated with the X chromosome of many species of Drosophila. Males carrying SR transmit predominantly sperm bearing the X chromosome. SR, therefore, has a very significant advantage in segregation. This paper provides an experimental analysis of the role of virility selection in preventing the fixation of SR. SR males are found to suffer substantial virility ...
متن کاملModifier Genes of the Sex Ratio Trait in Drosophila pseudoobscura.
The msr trait of Drosophila pseudoobscura occurs when "sex-ratio" males produce a very high frequency of null-X sperm which give rise to sterile male (X/O) progeny. The trait involves dramatically lowered fecundity due to spermiogenic failure. The msr trait is multigenic and the genes are located on autosomes II, III and IV of the L116 laboratory stock. This stock also carries genes on the Y ch...
متن کاملSex ratio, sex change, and natural selection.
We describe the analogy between the theory of natural selection on sex ratio in newborn gonochores (which will not change sex), and on the age of sex change in sequential hermaphrodites (which are all born into one sex and change to the other later on). We also discuss the conditions under which natural selection favors sequential hermaphrodites over gonochores and vice versa. We show that, in ...
متن کاملNatural Selection: Sex Ratio
Natural selection acts strongly on the proportional numbers of male and female offspring among the progeny of adults. The equilibrium is often one at which males and females are produced in roughly equal numbers, but under certain ecological and genetic circumstances there may be dramatic population-wide biases, and even in populations with balanced sex ratios, parents are often selected to pro...
متن کاملSex Ratio Elasticity Influences the Selection of Sex Ratio Strategy
There are three sex ratio strategies (SRS) in nature-male-biased sex ratio, female-biased sex ratio and, equal sex ratio. It was R. A. Fisher who first explained why most species in nature display a sex ratio of ½. Consequent SRS theories such as Hamilton's local mate competition (LMC) and Clark's local resource competition (LRC) separately explained the observed deviations from the seemingly u...
