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 ...

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 ...

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 ...
