EVOLUTION OF DIOECY and SEX CHROMOSOMES
Why are there two sexes in certain species, instead of one hermaphroditic sex? Why are Y chromosomes shorter than X chromosomes, but only in certain lineages? I propose that differences between sexes are initially determined by differential methylation in nuclear DNA between females and males, driving Muller’s ratchet. Methylation of promoters suppresses transcription, including loci coding for...
متن کاملSex Allocation: Evolution to and from Dioecy
Sex allocation in hermaphrodites should evolve in response to changes in the frequency of unisexuals. As predicted, it has now been demonstrated that hermaphrodites respond to the removal of males from experimental plant populations by increasing their allocation to male function.
متن کاملDioecy and the evolution of sex ratios in ants.
Split sex ratios, when some colonies produce only male and others only female reproductives, is a common feature of social insects, especially ants. The most widely accepted explanation for split sex ratios was proposed by Boomsma and Grafen, and is driven by conflicts of interest among colonies that vary in relatedness. The predictions of the Boomsma-Grafen model have been confirmed in many ca...
متن کاملMultiple Nuclear Gene Phylogenetic Analysis of the Evolution of Dioecy and Sex Chromosomes in the Genus Silene
In the plant genus Silene, separate sexes and sex chromosomes are believed to have evolved twice. Silene species that are wholly or largely hermaphroditic are assumed to represent the ancestral state from which dioecy evolved. This assumption is important for choice of outgroup species for inferring the genetic and chromosomal changes involved in the evolution of dioecy, but is mainly based on ...
متن کاملTheory for why dioecious plants have equal length sex chromosomes.
Dioecy and sex chromosomes almost certainly evolved from ancestral hermaphrodites that only possessed autosomes. There is a growing body of evidence that genes for female or male function were then epigenetically suppressed in some of these hermaphrodites, creating the first males or females and nascent sex chromosomes. The incipient sex-determining epigenetic signals, such as cytosine methylat...
