Even though genes are thought to be inherited evenly from both your mom and dad, studies now showed a higher percentage of genes expressed are from the father. Researchers ran tests with a group of mice that showed the highest diversity, making it more comparable to humans. This study consisted of interbreeding 3 strains of to create 9 different offspring. The offspring created were then measured on their level of gene expression of their tissues to examine how much was inherited by the mother/father mouse. The final testing showed that 60% of the mouse's genes were inherited from the father. The main feature examined in the mice was the father's impact on the offspring's brain. Researchers believe that because humans share a common ancestor with these mice that this inheritance may be true in all mammals.
With this new information known about a larger percentage of inheritance coming from the father's gene, scientist's may have an easier time with diagnoses. If a mother has a bad mutation it will become less likely that it will be expressed. But if a father's genes contain a mutation then it may allow scientists to predict diseases easier and have patients of certain diseases be treated with a better outcome. If scientist can go further into this research and determine what genes from the father are most likely to be expressed then diagnosing a child may become easier.
