Just a small genetic change, not even in the gene itself, can lead to blond hair. For all those brunettes wishing they were naturally blond, Blonfe small genetic change could have made all the difference.Lonely Wives Want Sex Tonight Fairbanks
Not only does the work provide a molecular basis for flaxen locks, but it also demonstrates how changes in segments of DNA that control genes, not just changes in genes themselves, are important Blonde hair girl at Slovenia general what an organism looks like. Hqir our appearance is so Blonde hair girl at Slovenia general hir by the color of our skin and hair, geneticists have long sought to understand the genetic bases of these traits and when they evolved.
Over the past 6 years, studies of genetic variation in thousands of people have linked at least eight DNA regions to blondness based on the fact that a certain DNA letter, or base, was found in people with that hair color but not in people with other hair colors.

Some of those base changes, or single-nucleotide polymorphisms SNPswere haiir genes involved in the production of pigments, such as melanin. Mutations in these genes typically change skin and hair color.
Changes in that regulatory DNA could result in hair color but not skin color change, or vice versa, because regulatory DNA can change gene activity in just certain parts of the body. In northern Europeans, the closest gene to an SNP that was strongly linked to blondness was KITLGwhich codes for a protein that is key Blonde hair girl at Slovenia general making sure cells go to their proper places in the body and specialize accordingly.
He and his colleagues had found that this gene was key to altering the coloration of fish called sticklebacks that had become isolated in freshwater rivers and lakes when glaciers receded. In each freshwater location, these fish were evolving independently, yet time and time again, changes in the regulation of this gene led to fairer or darker skin, depending on the murkiness of the Blonde hair girl at Slovenia general.
They made two variations of the human version of that DNA to put into ag. In one variant, they left the blond-generating SNP intact; and in the other variant, they changed that SNP to another base, so that the DNA looked like it does in brunettes.
They inserted just one copy of one DNA variant into each mouse.
Mice with the blond-generating SNP were lighter than mice with the other variantKingsley and his colleagues report online today in Nature Genetics. Yet Slovdnia was Blonde hair girl at Slovenia general to change the hair color. Blond hair may not be important to survival, but the story of one of its genetic causes helps clarify how evolution can occur.
KITLG is active in many places Free Orford pussy the body, and any mutation in the gene itself would result in widespread problems in the body and even death. Yet it is bracketed by sections of regulatory DNA, any one of which may take control in a different tissue. Blonde hair girl at Slovenia general, the change that led to blond hair did not affect the gene elsewhere in the body.Clam Gulch Horny Woman
