because the genetic material of the food they collect--the nectar--may have already been contaminated heavily from contact with GMO material that has escaped from dedicated-GMO farms. bee larvae do feed on honey
@shutterpod...serioiusly genetic modifications happen each time an animal or plant reproduces. Domesticated animals and cultivated crops are genetically different from the wild varieties they were derived from
Isn't genetic engineering merely a minor extension of traditional breeding practices? A. No. While farmers have used crossbreeding techniques to cultivate crop
and animal species with desired characteristics genetic engineering represents a radical departure from this practice. Crossbreeding can only occur within closely-related life forms.
Genetic engineering allows scientists to cross the species barrier mixing genetic material among of animals plants and microorganism.
The offspring of genetic engineering would never be found in nature. For example fish genes have been placed in tomatoes human genes in tobacco bacteria in corn and viruses in squash and fruit.
keep it simple stupid your statement genetic modification happens in the lab only is wrong.
I contrasted natural breeding to direct genetic modification/manipulation...The statement wasn't wrong it simply wasn't to your liking.

The New york times piece is a fascinating read bringing in the emotions around genetic engineering as well as the ominous danger to the fruit.
Genetic biologists have been trying to combine the strengths of each for some time now and researchers have managed just to compare the DNA
Theoretically the comparison could allow genetic biologists to pick out exactly which genes they want to splice to have desired the effect on the tomato.
But if genetic modification can give us a tomato that's got the taste and texture of an heirloom with the ease of growth lack of disease and ease of transport of a hothouse tomato we're on board.

Shannon Pinson a USDA geneticist tells Popular Science. In the future the USDA hopes such knowledge will help breeders create rice varieties that may help with mineral deficiencies in developing countries where rice is a staple.
Most of the rice as well as the corn and wheat that Americans buy in grocery stores have benefitted from these non-engineering genetic techniques Pinson says.
even if it's bred using the genetic knowledge Pinson develops may still be grown organically. Two roughly half of the rice the U s. grows is exported

just by chance no genetic variants have been born that lacked the detrimental traits or more likely altering one's esophagus to prevent hiccups would entail unacceptable changes in another part of the anatomy.
With the lack of selective pressure of predation or disease in many developed countries the minor genetic mutations that would give rise to evolutionary traits under natural circumstances simply stay in the population and compound.

so its going to have to settle with a member of another already existing species. This is an unavoidable roadblock for evolution this new bird's genetic material is added merely to that of an existing species where evolution requires it branches off on it's own.
and even now should see more genetic variation. Yet despite significantly greater pressure to survive they don't.
If you ignore that environmental pressures don't make genetic mutations that almost all genetic mutations are very bad
which means its not another species. When it all comes down to it a change has to be made that makes the animal not able to reproduce with the previous genetic set up.

When it comes to chickens geneticist Carl Schmidt is working to prepare the most-dined-upon North american breeds to withstand greater heat stress in coming decades.
Three years into the project the geneticists have gathered just about all the data they ll need and will spend the next two years analyzing it:
in order to determine the best approach for getting those good heat-resistant genes into American chickens without taking along all the genetic baggage as Schmidt calls it that s unnecessary to duplicate in the hybrid chickens.
and analyzed the genetic codes of these hardy African and South american poultry they hope American producers will crossbreed them to North american birds.
Scientists have developed incredibly precise techniques for genetic engineering. For example they're now able to change just one base pair in an animal's DNA code ne pair of letters in an animal that has billions of such pairs.
The end result would be engineered pigs that farmers could have made through generations of careful breeding geneticists argue.
But hope springs eternal among genetic engineers apparently. However you may feel about genetically modified foods we thought you would enjoy this foray into the science of it all.
In both cases researchers sidestepped any actual genetic engineering by simply introducing foreign tissue and letting it take root.
To do that requires a tremendous amount of genetic engineering says Lewis. Until scientists achieve a profound understanding of human and animal genomes superhuman hybrids will remain little more than a cinematic confection.

#Molecular evolution of genetic sex-determination switch in honeybeesit's taken nearly 200 years but scientists in Arizona and Europe have teased out how the molecular switch for sex gradually
The first genetic mechanism for sex determination was proposed in the mid-1800s by a Silesian monk named Johann Dzierson according to the study's co-author and Arizona State university Provost Robert E. Page Jr.
However how this system of haplodiploid sex determination ultimately evolved at a molecular level has remained one of the most important questions in developmental genetics.
In the December issue of Current Biology Page and Martin Beye lead author and professor with the Institute of Evolutionary Genetics in the University of Duesseldorf Germany and their collaborators laid out the final pieces of how these systems
Also Page and former graduate student Greg Hunt identified genetic markers--well-characterized regions of DNA--close to the complementary sex determining locus to allow gene mapping.
In addition Hunt and Page found that the honey bees'high recombination rate--the process by which genetic material is mixed physically during sexual reproduction--is the highest of any known animal studied
'The identification of palm individuals at the species level as well as the detection of hybrids can also be very helpful for preserving the genetic characteristics.

#Controlling parasitic worms with genetic selectionhelminths are gastrointestinal parasitic worms that have become a major concern and source of economic loss for sheep producers around the world.
One such strategy is genetic selection. Certain breeds of sheep are more immune to helminths than the conventional breeds used in Canada
A key advantage to applying genetic selection rather than chemicals to get rid of the worms is that it is permanent
With today's developments in genomic selection breeding sheep for helminth resistance can be achieved efficiently without adversely affecting other economically important traits explained Niel Karrow lead author of the paper a researcher at the Centre for Genetic Improvement of Livestock at the University of Guelph.
Since the 1980s differences in the appearances of male and female birds have been seen through a prism of genetic correlation.

#Genetic mutation increases risk of Parkinsons disease from pesticidesa team of researchers has brought new clarity to the picture of how gene-environmental interactions can kill nerve cells that make dopamine.
For the first time we have used human stem cells derived from Parkinson's disease patients to show that a genetic mutation combined with exposure to pesticides creates a'double hit'scenario producing free radicals in neurons that disable specific molecular pathways that cause nerve-cell death
Having access to genetically matched neurons with the exception of a single mutation simplified the interpretation of the genetic contribution to pesticide-induced neuronal death.

This brings the genetic record into agreement with the archaeological record. Europe is where the oldest dogs are found.
The idea of wolves following hunter-gatherers also helps to explain the eventual genetic divergence that led to the appearance of dogs he said.
In research published in the journal nature in 2010 Wayne and colleagues reported that dogs seem to share more genetic similarity with living Middle Eastern gray wolves than with any other wolf population
The new genetic data have convinced him otherwise. When we previously found some similarity between Middle Eastern wolves
Wayne considers the new genetic data persuasive but said they need to be confirmed with an analysis of genetic sequences from the nucleus of the cell (roughly 2 billion base pairs)--a significantly larger sample than that found in MITOCHONDRIAL DNA (approximately 20000 base pairs).
This is challenging because the nuclear DNA of ancient remains tends to become degraded. While Wayne plans to pursue this follow-up research he said he does not expect a nuclear genome analysis to change the central finding.
