Evolution of eukaryotic centromeres by drive and suppression of selfish genetic elements
T Kumon, MA Lampson - Seminars in cell & developmental biology, 2022 - Elsevier
Despite the universal requirement for faithful chromosome segregation, eukaryotic
centromeres are rapidly evolving. It is hypothesized that rapid centromere evolution …

Chromosome-level assembly reveals extensive rearrangement in saker falcon and budgerigar, but not ostrich, genomes
Background The number of de novo genome sequence assemblies is increasing
exponentially; however, relatively few contain one scaffold/contig per chromosome. Such …

Chromosomal speciation in the genomics era: disentangling phylogenetic evolution of rock-wallabies
The association of chromosome rearrangements (CRs) with speciation is well established,
and there is a long history of theory and evidence relating to “chromosomal speciation.” …

Cell biology of cheating—transmission of centromeres and other selfish elements through asymmetric meiosis
Abstract Mendel's First Law of Genetics states that a pair of alleles segregates randomly
during meiosis so that one copy of each is represented equally in gametes. Whereas male …

Ancestral reconstruction of karyotypes reveals an exceptional rate of nonrandom chromosomal evolution in sunflower
Mapping the chromosomal rearrangements between species can inform our understanding
of genome evolution, reproductive isolation, and speciation. Here, we present a novel …

Repetitive DNAs highlight the role of chromosomal fusions in the karyotype evolution of Dascyllus species (Pomacentridae, Perciformes)
The Dascyllus genus consists of 11 species spread over vast regions of the Indo-Pacific,
showing remarkable reductions in the diploid chromosome numbers (2n). The present study …

Origin of a giant sex chromosome
Chromosome size and morphology vary within and among species, but little is known about
the proximate or ultimate causes of these differences. Cichlid fish species in the tribe …
