What is the largest unit in which gene flow is possible?

genus, in some instances organisms can create gene flow.i.e. horse and mule. or dog and wolf (which are not same species.)

South America's Amazon River is the world's largest because it carries more water to the sea than any other river. The Amazon's discharge at its mouth is approximately 7 million cubic feet per second.\nThe Amazon is the world's second longest river as well, coming in just a tad shorter than the Nile River at 4,049 miles (6,516 kilometers) long.

ESU is Evolutionary Significant Unit.... referring to a group which is fairly distinct and reproductively isolated from anything else that might be considered similar... or rather that it doesn't interbreed with other close species (and typically that there isn't anything much like it anywhere near)...  Seems more of a conservation biology term to me...\n\nAs for the MU .... thats Map Unit ... and refers to some stuff to do with distances with genetic marker loci along chromosomes.... something beyond my meagre knowledge to explain.

The Nile is credited as the longest river in the world. Its main source is Lake Victoria, in east central Africa. From its farthest stream in Burundi, in eastern Africa, it extends 6,695 km (4,160 miles) to Egypt.

I've answered a similar question in the past\n\nhttp://answers.yahoo.com/question/index;_ylt=ApDo1VHr18AJSQm6WOxC_8Dsy6IX?qid=20061028024332AAKbYkD\n\nor copy pasting...\n\n"The more bulky the molecule the harder it is for it to move through the gel pores and thus the slower it will run.\n\nThe order in a gel would be\ncircular nicked (so there is no supercoiling)\nlinear\nsupercoiled\n\nObviously from this order supercoiled is the fastest running, though sometimes it can run at the same height as linear.\n\nThe migration of linear DNA is the one representative of the actual size."

The anunaki supposedly engineered modern humans and we are The 7Th genetic experiment on earth. very interesting ideas i keep an open mind on all things until somethings proved  100%. fact .            good question

I'd say no. Location has nothing to do w/ genes UNLESS you isolate the people in each city so the people inside them cannot reproduce with other people from different cities. Over time you MIGHT be able to see little distinctions because the dominant traits will have been passed around to everyone and then they will express it.

Mammoth Cave now has 367 miles of mapped passage. The above anwser is out of date. Mapping in the cave continues on a regular basis. Mammoth may be the longest but may not be the largest in terms of volume:\n\nHere are the long and deep cave lists for the world:\nhttp://www.pipeline.com/%7Ecaverbob/wlong.htm\nhttp://www.pipeline.com/%7Ecaverbob/wdeep.htm\n\nAt present cave mapping techniques do not allow mapping volume of the cave since the passages are so irregular. Mammoth might still hold the record, but some other caves would probably move far up the list because of very large rooms. \nHere is what is considered the world's largest cave in terms of volume, located in Borneo, known as the Sarawak Chamber:\nhttp://www.e-borneo.com/travel/tours/eb-ml.html\n\nHere is another very large cave (in volume) in Oman:\nhttp://magma.nationalgeographic.com/ngm/0304/feature2/zoom3.html

Its called the centromere, if i understand your question correctly

Yes subject to Nat. Sel. as u can still see on Sudan swamps, tallest community of humans an the world, or Peruvians living high on the Andes where they have extra coding capacity for Hemoglobin.\n\nThe conditions you describe were studied theoretically by Hardy and Weinberg, so these conditions are called "Hardy-Weinberg equilibrium" and you can search it on almost any college level ecology text.\n\nWhat happens to the gene pool on such conditions? with no nat. sel., all "expensive" genes, ones that take a lot of energy to work, disappear or reduce strongly their presence, and a proff is that Capsicum annum or chili as you call it, when taken to spain from Mexico, lost its cappacity to produce capscin, the spicy oil that gives chili its strenght and in nature is a defense versus herbivorous insects not present on spain. And so on.

Easy, the Amazon has the largest capacity in the world at around 219,000 cubic metres per second and a drainage basin of almost 7,000,000 square kilometres, whilst the second place Congo has only 41,800 cubic metres per second and a 3,680,000 square kilometre drainage basin.  The Amazon wins handily.\n\nHope this helps.\n\nNote: The Nile, though the longest river in the world with an impressive 3,600,000 square kilometre drainage basin doesn't come close to the average discharge of the Amazon, at only around 5000 cubic metres per second.

Try a rough DNA isolation, some things u need are detergent, lemons, and a sample like onion.\n\nSimple diffusion experiments with onions, salt, water, etc..

At the closest, about 400 million miles. \nAt the furthest, about 600 million miles.
