Genome structure and emerging evidence of an incipient sex chromosome in Populus. Silene latifolia is a dioecious species with separate male and female individuals which harbours XY sex chromosomes and constitutes an important model for sex determination in plants.
Non-transmissibility of the Y chromosome through the female line in androhermaphrodite plants of Melandrium album. Footprints of inversions at present and past pseudoautosomal boundaries in human sex chromosomes. Substances Genetic Markers. Because of the large number of the sexually dimorphic traits, it is reasonable to suppose that a master gene s for their control is located on the Y chromosome and plant sex determination and sex chromosomes pic in Burbank autosomal genes with sex-limited expression are involved in sexual dimorphism in S.
One approach is to directly search for sex-linked genes Guttman and Charlesworth, Protoplasma: — Lloyd, DG The low frequency and scattered taxonomic distribution of dioecy and sex chromosomes suggest that cosexuality is the ancestral angiosperm state Figure 1 Charlesworth, ; Renner and Ricklefs, Sexual dimorphism in white campion: complex deletion on the Y chromosome results in a floral asexual type.
