The latest research claims all there are 60 to make a variation everybody's genes newly
According to daily June 13 of scientific net, in the genome that we get from parents, all there are 60 to make a variation everybody's genes newly. Surprising figure this, by the intersection of foundation and the intersection of mulberry and the intersection of Georgia and research institute, Canada and the intersection of U.S.A. and many of the intersection of university and cooperation, nurse of department, Weir of British, make a variation through measuring the human complete genome directly, and and obtain after parents' comparative analysis of both sides. Researchers utilize " Genome plans of a thousand people " Gene order-checking technologies the whole,last child genetic mutation quantities relative to their parents of two piece family, the result reveals: DNA (DNA) How much the code will change, determined by the difference between parents DNA of both sides, " the new one " Variation is not the parents both sides. Former the intersection of mankind and person who make a variation measure, consider gender differences are and average among not taking the place of more, so unable to measure until some particular to take the place of between the border, get particular child a certain take place from parents what make a variation newly. Two families as the research objects are both made up of parents both sides and a child. Through gene order-checking, researchers look for those new variation not had in the child's DNA in their parents' genome, have found nearly 6000 possible variation. They make a variation, divide two kinds into these, one happens while parents' sperm or ovum will produce, another kind takes shape while the child grows up. The variation rate of the sperm or ovum is essential in the evolution. In a family, 92% of the variation stems from father, but in another family, only 36% of the variation stems from father. The general view before this thinks, in all families, the majority makes a variation and comes from father, because genome duplicate need more times by an ovum duplicating by one sperm. And new research reveals, in some families, the majority makes a variation and comes from mother; And in other families, the majority makes a variation and comes from father. Reach and play explaining in the cooperation leader of this research project, Aiwa of Philip of University of Montreal of Canada: "On average, in every generation, every 100 million DNA codes have a variation, should find these and make a variation just as dragging for the needle with the sea newly. But utilize experimental technique and new analysis algorithm developed newly, we can examine the theory in the past now. " This result is against researcher's expectation, because of in two families, they have only measured a child, it is unable to draw the precise conclusion. Researchers say, the new mutant quantity causes the individual differences between sperm and ovum in the body of parents that variation course difference cause between parents, need, through study more family, could find answer, analyze the intersection of parents and age, environmental difference factor to influence that lead to the fact of making a variation etc. newly further also.
