You set up the following dihybrid mapping cross in fruit flies. 
P e+e+ roro cq cq x ee ro+ro+ cq+cq+. After backcrossing F1 males to ee roro cq cq females, you get the following results: gray body, rough eyes, claret eyes 576; ebony body, smooth, red eyes 564. How can you explain this result?

Major pathway of complement activation is involved such as
I. Classical pathway
II. Lectin pathway
III. Alternative pathway
These pathway involved
a. proceeds through the activation of a C3 convertase composed of C4b and C2a
b. Involved spontaneous hydrolysis or pathogenic surface
c. part of the adaptive immune response since it begins with the formation of antigen-antibody complexes.
d. Lectin proteins that recognize specific carbohydrate components primarily found on microbial surfaces—PAMP
