Special Issue “The Evolutionary Life Cycle of Sex Chromosomes”

A issue that is special of (ISSN 2073-4425). This issue that is special into the area “Population and Evolutionary Genetics and Genomics”.

Unique Problem Information

Intercourse chromosomes represent a component that is specialized of genome. They perform a crucial part in basal procedures such as for instance intercourse dedication, but they are additionally frequently associated with emergent evolutionary phenomena such as for example speciation. Exactly How intercourse chromosomes are born, mature and perish is an important concern in modern biology that is evolutionary. Intercourse chromosomes are thought to evolve from a typical set of autosomes, originating whenever an autosome set acquires a sex-determining function. exactly exactly How and just why this change occurs continues to be mostly unknown. Intercourse chromosomes undergo many modifications, such as for example recombination suppression, degeneration by accumulation of repeated DNA and transposons, dosage payment to balance the gene items of degenerated genes, and gene trafficking to and from other chromosomes. This usually yields a set of highly-differentiated chromosomes, certainly one of which exhibits the decay that is extensive of late-stage intercourse chromosomes. Fundamentally, this decrepit chromosome might even be lost, causing men and women having various variety of chromosomes. Much stays to be found concerning the processes that shape sex chromosomes, however the revolution in genomics, transcriptomics along with other associated technologies enables us to review the evolution of sex chromosomes in unprecedented information. This dilemma will deal with questions regarding the lifecycle of intercourse chromosomes across various groups that are organismal. < (more…)
