cred ca nu are nicio legatura ! |

RE: Cum iti explici atunci ca se intampla ca ramuri intregi de familii sa fie constituite din alcoolici ?
De cate ori nu se spune despre cate o familie: "Astia ? niste betivi !".
De ce in unele familii sunt multi betivi, si in altele deloc ? Sa fie doar intamplarea ? |

Tine de educatie, nicidecum de genetica. |

RE: OK. Oare "raspunsul" la educatie nu e si el oare mostenit genetic ? |
| Cipi | Sâmbătă, 23 iul 2011 12:19 |
RE: Ba da, dar foarte putin. O educatie puternica anuleaza orice (sau aproape orice) tentativa naturala de a iesi din tiparul familiei. |

Eu cred ca e vorba doar de ...puterea exemplului. Ce poti invata de la niste parinti alcoolici?
Sa bei, evident! |

OK, n-am vrut sa va dau de la inceput chestia asta, vroiam sa vad intai ce spuneti.
Asadar:
"Children of alcoholics are four times more likely than other children to become alcoholics, according to the American Academy of Child & Adolescent Psychiatry, but environmental factors could be a factor in many of those cases.
Family, twin and adoption studies have shown that alcoholism definitely has a genetic component. In 1990, Blum et al. proposed an association between the A1 allele of the DRD2 gene and alcoholism. The DRD2 gene is the first candidate gene that has shown promise of an association with alcoholism (Gordis et al., 1990)."
Researchers at the University of California at San Francisco (UCSF) are using fruit flies to find the genetic causes of alcoholism, the Wall Street Journal reported. According to the scientists, drunken drosophila fruit flies behave the same way human do when they are drunk. In addition, a fruit fly's resistance to alcohol appears to be controlled by the same molecular mechanism as humans.
Hugo Bellen, a geneticist at Baylor College of Medicine in Houston, Texas, said the study "lays the foundation for a genetic approach to dissecting the acute, and possibly the chronic, effects" of alcohol in people. |

In another study scientist selectively bred two strains of mice: those that are not genetically sensitive to alcohol, and those that are acutely genetically sensitive to it. The two strains show markedly different behavior when exposed to identical amounts of alcohol.
The sensitive mice tend to lose their inhibitions and pass out rather quickly, earning them the nickname "long sleepers." "Short sleepers" are mice that are genetically less sensitive to alcohol. They seem to lose fewer inhibitions, and tolerate the alcohol for longer before they pass out.
"Alcohol consumption is influenced by a combination of environmental and genetic factors," said Gene Erwin, PhD, professor of pharmaceutic sciences at the CU School of Pharmacy, "This study indicated that genetic factors play more of a role, and we're trying to understand the power of those genetic factors."
If alcoholism can be traced to a particular gene or combination of genes, how can the information be used?
"These genes are for risk, not for destiny," stressed Dr. Enoch Gordis, director of the National Institute on Alcohol Abuse and Alcoholism. He added that the research could help in identifying youngsters at risk of becoming alcoholics and could lead to early prevention efforts.

eu beau de sparg desi ai mei nu consuma alcool, asta inseamna ca poate nu-s fiul lui tata ? :D |

nu cred ca este vorba de mostenire. iti place, o faci! si o faci in exces de cate ori poti. <fuck the consequences> exemple avem peste tot in jurul nostru, in mai multe subiecte de exces in ceea ce parintii nostri pobabil ca nu aveau curajul/tupeul/bgarea de picioare de azi. roll on! |

Se transmite genetic alcoolismul ?
