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 ...

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 ...

A research collaboration based in Kumamoto University (Japan) has clarified how homologous chromosome pairing--a process necessary for sperm and egg formation where paternally- and maternally-derived ...

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 ...

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 ...

Common genetic variants affect the risk of abnormalities in chromosome number (a phenomenon known as aneuploidy), a major cause of pregnancy loss, according to a study published in Nature. The ...

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 ...
