Silene latifolia, also known as White Campion, is a dioecious plant with an XY sex-determination system. It has a Y chromosome of approximately 550 megabases (Mb), much larger than typical Y ...

Heredity - Recombination changes at the boundaries of fully and partially sex-linked regions between closely related Silene species pairs Skip to main content Thank you for visiting nature.com.

The X and Y chromosomes of dioecious Silene species are morphologically distinct, like those of mammals, and they also have a PAR and a nonrecombining region.

All diploid Silene species have the same chromosome number (n = 12), suggesting that translocations of whole chromosomes have not contributed to the enlarged X and Y, ...
