Support Center Support Center. Here, we reflect on more than a century of research into flowering plant sex determination, placing a particular focus on the foundational genetic and cytogenetic observations, experiments, and hypotheses. Dansk Bot Arkiv. Our earlier study established an association between the Y chromosome and coronary artery disease CAD in two separate British cohorts using reconstruction of the Y phylogeny.

This has 2 important consequences; first, the proliferation of repetitive DNA can interfere with gene function, leading to the degeneration of a sex chromosome, and second, by making them intractable regions for highly contiguous genome assembly and annotation due to the high degree of similar or near-identical repetitive DNA.

An immune-related gene evolved into the master sex-determining gene in rainbow trout, Oncorhynchus mykiss. Tablet—next generation sequence assembly visualization. Mol Genet Genomics. Theor Appl Genet. Model-based analysis, maximum likelihood phylogenetic reconstruction, and principal component analysis PCA all confirm the previous finding of three distinct populations of Y chromosomes Fig.

Derivative melting curves of four SNP sex-linked loci in five female and in five male individuals. Several small case—control studies conducted in the s found associations between the 47,XYY karyotype males carrying two copies of the Y chromosome and criminality 8 and between the length of Y and physical activity levels.

The extremely low sequence diversity of the X-linked sequences from wild dioecious populations, together with the lack of population structure, suggests that hitch-hiking processes have reduced diversity in the populations surveyed here. Stevens named the chromosome "Y" simply to follow on from Henking's "X" alphabetically.

All SNPs significantly associated with sex were in strong linkage disequilibrium despite the fact that they were mapped to six different chromosomes (plus 3 unmapped scaffolds) in version of the reference genome. We show that this is likely due to genome misassembly. The Cited by:
