Satellite DNA represents one of the most fascinating parts of the repetitive fraction of the
eukaryotic genome. Since the discovery of highly repetitive tandem DNA in the 1960s, a lot …

Phenotypic plasticity, the property by which living organisms express different phenotypes
depending on environmental conditions, can impact their response to environmental …

Sex differences in aging occur in many animal species, and they include sex differences in
lifespan, in the onset and progression of age‐associated decline, and in physiological and …

Polyploidy or whole genome duplication (WGD) is a major contributor to genome evolution
and diversity. Although polyploidy is recognized as an important component of plant …

Changes in chromosome numbers may strongly affect reproductive barriers, because
individuals heterozygous for distinct karyotypes are typically expected to be at least partially …

The past decade has seen the availability of insect genomic data explode, with
mitochondrial (mt) genome data seeing the greatest growth. The widespread adoption of …

Chromosome rearrangements are arguably the most dramatic type of mutations, often
leading to rapid evolution and speciation. However, chromosome dynamics have only been …

Genetic degeneration is an extraordinary feature of sex chromosomes, with the loss of
functions of Y-linked genes in species with XY systems, and W-linked genes in ZW systems …

In many multicellular eukaryotes, heteromorphic sex chromosomes are responsible for
determining the sexual characteristics and reproductive functions of individuals. Sex …

The study of sex determination and sex chromosome organization in nonmodel species has
long been technically challenging, but new sequencing methodologies now enable precise …
