Opinions differed as to how the mental disability passed from parents to children. Several theories have emerged. Some researchers hypothesized that mental disability is a disease such as syphilis and tuberculosis transmitted by a bacterium found in the blood of one or both parents. It results from drinking alcohol, drugs, lead poisoning, in the blood.
Other researchers have hypothesized that mental retardation is transmitted by genes in the same way as other physical and psychological characteristics.
Therefore, we see that the second method or hypothesis is better than the first because mental disability is not a disease and there is no known microbial, but the second hypothesis of gene inheritance is a well-known assumption because genes carry genetic characteristics, Which comes from his parents and grandparents.
Mental retardation is inherited when the male sperm penetrates the outer envelope of the female egg until its nucleus clears its nucleus. The first cell, which consists of 46 kr and a mosquito (23 kr, marked by the father and 23 kr and marked by the mother) is created.
Each chromosome carries hundreds of genes that carry genetic traits, passed on from parents to children. If the genes in the parents are identical, the genetic traits carried by the genes appear to be authentic. If the genes are not identical, the genetic characteristic will reappear in future generations. This means that there are genes with mental disability in both parents that make the probability of mental disability in their children significant. This possibility is reduced if one parent carries the property and the other does not, because in this case either the child's mental disability appears or disappears to appear in Grandchildren when appropriate conditions are available (Dr.Marsi 1996)
Therefore, prenuptial persons must examine themselves in the hospital to ensure that there are no genetic factors leading to genetic diseases, including mental disability.
