The parents hereditary material has different function

The parents hereditary material has different function
Xinhua News Agency London 10 Cable of the 28th of moon (reporter is yellow) The child has inherited parents' gene, but the child is different from parents, this is because parents' gene will be changed through recombinating etc. when heredity is given children. A latest research reveals, in this change, the function of father and mother hereditary material is different.
Britain>The magazine publishes studying to say, the researchers of the genetic research institution deCODE of Iceland analyzed the gene of the parents and child in 1.5 ten thousand families on the 28th, have found this phenomenon.
Say, have two sets of hereditary materials in everybody's genome, one set comes from father, another set comes from mother. Heredity recombinates meaning, man or women body is inherent while forming the sperm or ovum, these two sets of hereditary materials will be separated, some of parts will be recombinated alternately, form a new hereditary material, whether sperm or ovum, all only contain the hereditary material after recombinating and changing of ways to do things. When the sperm combines with the ovum, a hereditary material that they carry respectively will be connected to together and recombinated, thus form the child's genome. But discover this time, in this course, the function of the parents hereditary material is different, the hereditary materials of one party of father change in genetic inside more, produce the new gene, and the hereditary material of mother's party is mostly that the seat between the gene changes.
Lead card Rister of this research to be all and loose pointing out, the way in which the hereditary material not merely recombinate of parents' both sides is with particular emphasis, the intensity recombinated is different too. The intensity that the hereditary material recombinates is higher than sperms in the ovum. Important reason to produce the genetic difference and thereupon cause the mankind to be diversified because of the hereditary recombination, look from angle recombinated in heredity, women's contribution in promoting humanly and diversifiedly should be big to men.
However, the reason causing genetic difference and the mankind to be diversified, except that heredity is recombinated, there is gene mutation,etc., and study to reveal, the gene mutation intensity of the sperm should be higher than the ovum. Stevan expresses loose : " It's hard to tell where party man and woman contributes greater on the human variety, but can find out man and women promote mankind's diversified development in different way.
