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 DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key ...

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 ...

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 ...

Recombination, the exchange of DNA between maternal and paternal chromosomes during meiosis, is an essential feature of sexual reproduction in nearly all multicellular organisms. While the role of ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

Geneticist and computational biologist, Meixia Zhao studies transposable elements — also known as “jumping genes” — using maize as a model system. She joined Miami University in fall 2018 as assistant ...
