They are also responsible for many of our characteristics, such as our eye colour, blood type or height. We have thousands of genes. We each inherit two copies of most genes, one copy from our mother Griffith finds a ‘transforming principle.’ . Griffith experimented with the bacteria that cause pneumonia.. He used two forms: the S form (deadly) and the R form (not deadly).. A transforming material passed from dead S bacteria to live R bacteria, making them deadly.. Lecturer 7 . Dr. . Shaimaa. .
