Genome duplication probably gave biodiversity a decisive evolutionary boost. A Chinese-German research team led by Axel Meyer from the University of Konstanz has now investigated the early phases of ...

Scientists report adaptive divergence in cryptic color pattern is underlain by two distinct, complex chromosomal rearrangements, where millions of bases of DNA were flipped backwards and moved from ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 chromosomes ...

Chromosomal rearrangements involving additional material in individuals with phenotypic alterations usually result in partial trisomy, often accompanied by partial monosomy. To characterize ...

Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies ...

Revealing the limitations of cloning, researchers who repeatedly cloned mice for two decades have discovered that such serial duplication triggers grave genetic mutations that accumulate over the ...

Nowadays, many different cytogenomic approaches can be used to obtain hints on chromosomal changes in primary material or cell lines. Chromosome microarrays (CMA) and optical genome mapping (OGM) can ...

To Shakespeare’s Hamlet we humans are “the paragon of animals”. But recent advances in genetics are suggesting that humans are far from being evolution’s greatest achievement. For example, humans have ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...
