According to the punnet square for this cross, what percentage of offspring is predicted to have blue feathers?

it would be the percentage of food eaten by the flock

i remember doing this lab

not sure if this what   you'r looking for would be percent composition

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
