Low frequency of mouse t haplotypes in wild populations is not explained by modifiers of meiotic drive.
Cheaters sometimes prosper: distortion of Mendelian segregation by meiotic drive.
551) argue more recently that in many cases of meiotic drive
, there is selection at two levels.
Control of meiotic drive
of B chromosomes in the mealy bug Pseudococcus affinis (obscurus).
Sex-ratio drive is a particular case of meiotic drive
, where the driving factor(s) are located on a sex chromosome.
However, for loci that exhibit strong epistatic interactions, such as those involved in sex-ratio meiotic drive
and its suppression (Jaenike 1996), current levels of gene flow in D.
More recently, analysis of the "sex-ratio" meiotic drive
system in natural populations of D.
I examined the evolution of SR polymorphism for discrete and overlapping generations, in the absence of selection and with complete meiotic drive
We discuss one possible cause - environment-specific meiotic drive
(that is, environment-specific selection among developing gametes or gametophytes) that to our knowledge has not been recognized as a source of variation among pollen donors.
I found this overly pessimistic; analytical or simulation studies must make assumptions about such things as selection, drift, gene flow, and meiotic drive
, and these then permit modeling of demographic or genetic parameters that show conditions under which strongly underdominant rearrangements may be fixed, spread, and contribute to postmating isolation.
(preferential transmission of metacentrics) was suggested by Hausser et al.
One recently proposed evolutionary explanation posits that both Haldane's rule and large sex-chromosome effects results from genes that cause meiotic drive
(Frank, 1991a; Hurst and Pomiankowski, 1991).
