Sex is prevalent in nature and sex determination is one of the most fundamental biological
processes, while the way of initiating female and male development exhibits remarkable …

For decades, satellite DNAs have been the hidden part of genomes. Initially considered as
junk DNA, there is currently an increasing appreciation of the functional significance of …

Rye (Secale cereale) is closely related to wheat (Triticum aestivum) and barley (Hordeum
vulgare). Due to its large genome (∼ 8 Gb) and its regional importance, genome analysis of …

B chromosomes (Bs) are dispensable components of the genome exhibiting non-Mendelian
inheritance and have been widely reported on over several thousand eukaryotes, but still …

Sex chromosomes are generally derived from a pair of classical type-A chromosomes, and
relatively few alternative models have been proposed up to now. 1, 2 B chromosomes (Bs) …

African cichlids display a remarkable assortment of jaw morphologies, pigmentation
patterns, and mating behaviors. In addition to this previously documented diversity, recent …

The first gapless, telomere‐to‐telomere (T2T) sequence assemblies of plant chromosomes
were reported recently. However, sequence assemblies of most plant genomes remain …

Approximately 15% of eukaryotes contain supernumerary B chromosomes. When present, B
chromosomes frequently represent as much as 5% of the genome. Despite thousands of …

B chromosomes are enigmatic elements in thousands of plant and animal genomes that
persist in populations despite being nonessential. They circumvent the laws of Mendelian …

Numerous plants and animals harbor selfish B chromosomes that “drive” or transmit
themselves at super-Mendelian frequencies, despite long-term fitness costs to the organism …
