To test the effectiveness of these antibodies, the two researchers injected cells that belonged to one genetic population of mice into the leg muscles of mice from a different genetic population.
The researchers estimated heritability - what proportion of risk for a disease across a population is genetic - for Alzheimer's to be between 58% and 79%.
The principle would work, he says, for any species with a genetic structure to its population.
Many biologists see cloning as a last resort since, unlike sex, it does not increase the genetic diversity of a population.
But they call for special attention due to the implications of spread of radioactivity with long term consequences including genetic effects on the population and the long time span required to bring back normalcy to the environment.
The population has recovered, but the genetic diversity has not recovered so that all the Tasmanian devils that exist are so similar to one another genetically that their immune systems don't seem to be able to tell one from another.
Spokesman Ajantha Palihawadana said such captures would interfere with nature by removing some of the best genetic stock from the elephant population, including some with tusks which are relatively rare.
Despite their personal sturdiness and the immense range of their wanderings (they settled Europe and Asia from the Iberian Peninsula to the Altai Mountains of Siberia), the latest genetic studies indicate their total population never managed to reach six figures.
He said the differences from one population to another "cannot be accounted for either by genetic make-up or environmental influences".
He said there was no guarantee that introducing a specific genetic change would have much impact in a population which was subject to the effects of many other natural selection processes.
"Coupled with recent genetic data, our finding indicates that the Atlantic population -- and perhaps the world population -- are connected and may constitute a single population, " Skomal said.
CNN: Scientists discover winter home of world's second-biggest fish
An environmental remediation team could use qPCR to count the population of specific contaminant degrading microbes, or to assess the genetic biochemical pathways (e.g. microbial cellular machinery) that cause the degradation of environmental contaminants.
This, some scientists believe, leads to new illnesses formed by genetic mutation crossing the species barrier and entering the human population.
This, some scientists believe, leads to new diseases formed by genetic mutation crossing the species barrier and entering the human population.
There's a genetic heritage that has built strength and speed into the population and an infrastructure that's grown up to help make the most of those genes.
Third, researchers have focused on so-called gene-environment interactions, reasoning that some exposures that have relatively weak associations with breast cancer in the general population may have a much stronger effect in subgroups with a specific genetic make-up.
FORBES: After 40 Years Of Research, What Do We Know About Preventing Breast Cancer?
Genetic damage can do more than kill people in some limited population or area.
This means there are relatively few genetic combinations amongst them, and this makes them an ideal population for finding genes that cause a whole host of common disorders.
The researchers studied the genetic makeup of 50 patients with vCJD, approximately half of the population known to have the disease.
Genetic testing has been carried out to try to find further hybrids among the population there.
CNN: Lonesome George, last of the Pinta Island tortoises, dies
"The lower the population of wild salmon, the greater the risk is because it takes less and less genetic infusion to corrupt it, " he said.
Some scientists have argued that the winter conditions this would have induced could have posed an immense challenge to early humans and have pointed to some genetic studies that indicated our ancestors likely experienced a dramatic drop in numbers - a population "bottleneck" - around the time of the eruption.
But there are genes that are more likely to occur in Europeans, who are descended from a relatively tiny population that made its way up the continent, than in Africans. (There is also far more genetic diversity in Africa than anywhere else.) And sometimes these genes are medically important enough that guessing at their presence based on skin color is worthwhile to some doctors.
