What kind of friends made or relate to gene
Los Angeles, January 20 (Xinhua) ' Reporter's plateau) What kind of friend people choose to make, except reasons such as the personality, hobby,etc., may still relate to gene. One in U.S.A. discovers newly, has genes to have " asks with the gaseous phase " between the friends Phenomenon,too existence " suck " Phenomenon. The researchers of the American branch school in San Diego of University of California say on a new American " journal of national academy of sciences ", after getting rid of influence factors such as the race, gender,etc., the similar intensity of the genome between the friends stills have particularity, some genes are extremely similar, some genes are extremely different. After researchers analyze the data of two health research projects, draw the above-mentioned conclusion. These projects involve about 5000 people, has recorded interviewees' social network information, and a certain particular location lighted the difference on each gene in 6 particular genes, namely many attitudes (SNP) of single nucleotide . DNA (DNA) that SNP makes a variation because of the single nucleotide to cause Arrays are different, it is most general one in mankind's hereditary variation, it is a main source of the genome difference between men too. Researcher find as to a certain at the one gene to call DDR2, incline to have the same SNP between the friends; To a certain at the one gene to call CYP2A6, the intersection of SNP and instead than other National People's Congress difference between the friend. People did not know the concrete function of the above-mentioned two genes, but studied to reveal before at present, DDR2 gene relates to habit of getting drunk, and CYP2A6 influences medicine supersession and hormone of the human body to formate, relate to intensity that craving for tobacco and thinking are open. Researchers guess, people incline to make genome and one's own very similar or very different friend, advantage had that there may be a certain evolution. But the scientist proposes, it is very complicated that the gene influences the behavioral mechanism, there are too few DNA data involved in this research, convincingness is insufficient, also need deeper research.
