the egg contains one copy of the mothers genes. However, if the parents test negative for the mutation (meaning each persons test results found no mutation), the risk to the siblings significantly decreases but their risk may still be higher than an average risk. Usually, a gene called the DNA mismatch repair (MMR) gene finds and fixes the errors before they damage the cell.
