Transcription rates, however, can be strongly correlated between the two sexes, and thus compensation for dosage imbalance in the heterogametic sex may cause a detrimental overexpression of sex-linked loci in the homogametic sex Wright and Mank

  • Thank you for visiting nature.
  • The selfish gene theory postulates that natural selection will increase the frequency of those genes whose phenotypic effects ensure their successful replication. Generally, a gene achieves this goal by building, in cooperation with other genes, an organism capable of transmitting the gene to descendants.
  • Genomic analysis of many nonmodel species has uncovered an incredible diversity of sex chromosome systems, making it possible to empirically test the rich body of evolutionary theory that describes each stage of sex chromosome evolution.
  • Intragenomic conflict refers to the evolutionary phenomenon where genes have phenotypic effects that promote their own transmission in detriment of the transmission of other genes that reside in the same genome. However, conflict among genes in the same genome may arise both in events related to reproduction a selfish gene may "cheat" and increase its own presence in gametes or offspring above the expected according to fair Mendelian segregation and fair gametogenesis and altruism genes in the same genome may disagree on how to value other organisms in the context of helping kin because coefficients of relatedness diverge between genes in the same genome.

As we found no evidence for translocations between these chromosomes, it is most likely that two different sex determination mechanims are present in the two lineages, meaning that sex chromosome turnover has occurred recently.

Thus, gynodioecy as an intermediate stage can be assumed if the molecular mechanism identified through the analysis of the sex determination system of a dioecious species fit these predictions.
