Pathogen evades plant by penetration of surface layers directly using mechanical pressure or enzymatic attack, some pass through natural openings, such as stomata or lenticels, and others only enter through wounded tissue. Once inside the plant, one of three main attack strategies is deployed specific feature of interaction given;

A) Necrotrophy

B) Biotrophy

C) Hemibiotrophy

i) where the plant cells remain alive throughout infection

ii) where the plant cells are killed in advance of infection 

iii) extensive plant tissue damage at initial stages

iv) where the pathogen initially keeps cells alive but at later stages of the infection, kills them

Red kernel color in wheat results from the presence of at least one dominant allele of each of two independently segregating genes . Kernels on rr bb plants are white, and the genotypes R— bb and rr B— result in brown kernel color. Suppose that plants of a variety that is true breeding for red kernels are crossed with plants true breeding for white kernels produced F1 were allowed to selfing .what are F2 phenotype ratio ?
