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 ...

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 ...

For the first time, researchers have mapped where recombination occurs across the whole genome of the fruit fly Drosophila melanogaster after a single round of meiosis. As eggs and sperm, or gametes, ...

Researchers have quantified one of the most important and hard-to-measure phenomena in molecular evolution: the effect of genetic recombination on a species' capacity of adaptation. UAB researchers ...

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 ...

In a groundbreaking study, scientists from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) have ...

Genetics is a crapshoot. During sexual reproduction, genes from both the mother and the father mix and mingle to produce a genetic combination unique to each offspring. In most cases, the chromosomes ...

This is a preview. Log in through your library . Abstract Speciation via interspecific hybrids is very rare in animals, as compared to plants. Whereas most plants overcome the problem of meiosis ...
