When we think of mutations, most of us imagine point mutations, or regions within the DNA at which one to several bases are changed or deleted. However, deletion and duplication of larger ...

Whole genome duplication (WGD) is a common mutation in plants with profound evolutionary potential. While it is well-known ...

Duplication provides raw fuel for rapid evolution by creating back-up copies of parts of the genome. If mutations with harmful effects crop up in one of these copies, there’s always a spare ...

A mutation is a heritable change in the nucleotide sequence of an organism's DNA that ultimately serves as a source of genetic diversity. A single base change can create a devastating genetic ...

The study reveals how interactions between cryptic mutations can increase or decrease the number of reproductive branches on ...

Picture juicy red tomatoes on the vine. What do you see? Some tomato varieties have straight vines. Others are branched. The ...

The genomes of long-living, big-brained mammal species reveal that they carry more copies of immunity genes. Experts ...

A genetic mutation is a permanent change to the nucleotide sequence of a gene. More often than not, such genetic mutations are advantageous – they enable evolution and produce new desirable traits in ...

"Our discovery also explains the mystery of why a gene duplication expressed in most cells of the body could result in a disease that only affects one type of cell." ADLD is a rare and fatal genetic ...

Picture juicy red tomatoes on the vine. What do you see? Some tomato varieties have straight vines. Others are branched. The ...

But an unknown number of people who have the mutation that causes the duplication of the lamin B1 gene also have a duplication of the silencer – and they never develop the disease.
