In recent years, much attention should be paid to the inheritance subtle signs through the genetic code. If previously, scientists believed that traits are formed in the process of growth and development, but now a number of studies proves that every quality has its own genetic code.
Certain traits are passed on through the DNA of the bacteria. Data were installed in the study with laboratory rats. Transgenic animals were observed unique characteristics that could not be "programmed" genetic changes.
In the experiment, the scientists found bacteria Sutterellа that live in the gastrointestinal tract of animals. She, according to scientists, is responsible for the low level of antibodies in mice.
