I need some help! I answered the questions but I am a little hesitant about submitting it. Can you check my answers, please?

Answer 4

Plz do one question per post, i will help you with the first one for now

Answer 5

codominance is an expression of both alleles, which would in turn make it's phenotype appear "spotted"

incomplete dominance is the blending of traits

so which do you think the answer is now?
