-
Examine interfertility and what differences (if any) in recombination that results in.
-
As it is never paired with a partner, it escapes a process called recombination that shuffles the code of every other chromosome in each new individual.
-
The most important factor is recombination, which is largely responsible for the virtually inexhaustible supply of new genotypes in every generation.
-
Sexual reproduction allows genetic recombination, that is, the exchange of genetic material between parental chromosomes.

How faithfully the ancestral lines have met in the latest product, how mysteriously the joint characteristics of body and mind have blended, and how unexpected yet how entirely natural a recombination is the result -- these points are elaborated with cumulative effect until we realize at last how little we are dealing with an independent unit, how much with a survival and reorganization of what seemed buried in the grave.

-
Thanks to new insights over the past few months, we now know that minisatellites sit next to the drivers of genetic change, called recombination hotspots, where parental DNA is blended during cell division.

-
A preliminary genetic linkage map indicated that the DIP-locus lacks suppression of recombination, which is unique among all other map-based cloning efforts of apomeiosis to date.
-
This mixing process, called recombination, is what happens in animals during sexual reproduction.
-
Using yeast cells, the scientists studied protein molecules that have an important role in homologous recombination, which is one way that cells repair breaks in the DNA double helix.
-
The different distributions of insertions/deletions and SNPs are clearly related to the two different responsible mechanisms, namely recombination and point mutations.

qroqqa commented on the word recombination
Something that had long puzzled me was cleared up last night by a remark in Guth's The Inflationary Universe: the combination of nuclei and electrons 300 000 years after the Big Bang is called recombination simply because that is the standard term in (terrestrial) plasma physics, where of course scientists start with ordinary combined matter and ionize it. There is no implication in cosmology that the plasma had ever been combined before.
