It all just depends on what genes they carry. You can create a Punnet Square to determine the percentage of obtaining a specific disease.
Obligate symbiotic fungi that form associations with plants by entering their cortical cells without invading the plant cells membrane are called endomycorrhizae and include the genus Glomus. Many plants form associations called mycorrhizae with fungi that give them access to nutrients in the soil, protecting against disease and toxicities. In these associations the fungi are integrated into the physical structure of the root, where the fungi colonize the living root tissue during active plant growth.
This is determined by its atomic number. The atomic number of an element determines its protons. So for example....
The atomic number of Boron is 5, therefore....the protons are 5.
