New findings suggest an explanation for the century-old mystery of how chromosome recombination is regulated during sexual reproduction. In most higher organisms, including humans, every cell carries ...

In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

Scientists at deCODE genetics/Amgen have constructed a complete map of how human DNA is mixed as it is passed down during reproduction. The map marks a major step in the understanding of genetic ...

When the genomes of parents come together to create the genome of a child, their DNA recombines; similar parts are rearranged so that a child carries sections of their parents genomes that have been ...

Koalas suffered a massive population decline that left them with dangerously low genetic diversity. However, new genomic research suggests their rapid rebound may be helping reverse some of that ...

Koalas’ population comeback may be doing more than boosting numbers—it could also be rebuilding their lost genetic diversity.

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...

Virus variation has been the bane of Covid-19 control. No sooner has one wave of infection passed than a second arrives, evading prior immunity and even vaccines. Monoclonal antibody drugs effective ...

In most higher organisms, including humans, every cell carries two versions of each gene, which are referred to as alleles. Each parent passes on one allele to each offspring. As they are linked ...
