In species with genetic sex-determination, the chromosomes carrying the sex-determining
genes have often evolved non-recombining regions and subsequently evolved the full set of …

Sex chromosomes are widespread in species with separate sexes. They have evolved many
times independently and display a truly remarkable diversity. New sequencing technologies …

Summary White campion (Silene latifolia, Caryophyllaceae) was the first vascular plant
where sex chromosomes were discovered. This species is a classic model for studies on …

How do separate sexes originate and evolve? Plants provide many opportunities to address
this question as they have diverse mating systems and separate sexes (dioecy) that evolved …

Intralocus sexually antagonistic selection occurs when an allele is beneficial to one sex but
detrimental to the other. This form of selection is thought to be key to the evolution of sex …

The idea that sex differences in selection drive the evolution of suppressed recombination
between sex chromosomes is well developed in population genetics. Yet, despite a now …

Recombination suppression around sex-determining gene (s) is a key step in evolution of
sex chromosomes, but it is not well understood how it evolves. Recently evolved sex-linked …

Sex chromosomes have evolved repeatedly across the tree of life and often exhibit extreme
size dimorphism due to genetic degeneration of the sex-limited chromosome (eg the W …

An introduction is presented in which the editor discusses various reports within the issue on
topics including rise in biological reality of the assumptions underlying scans for selection …

In many species with sex chromosomes, the Y is a tiny chromosome. However, the
dioecious plant Silene latifolia has a giant~ 550-megabase Y chromosome, which has …
