Answer:
In codominance, two dominant genes express itself in appearance (phenotype). For example, In people with AB blood types, A and B are both dominant genes and both try to show themselves in blood type, which forms third blood type AB.
In incomplete dominance, the organisms with heterozygous genotype (Aa) will have a blended trait instead of showing dominant trait because dominant gene (A) cannot show itself necessarily in appearance (phenotype). For example, when a plant with homozygous red flower (dominant and AA) is crossed with white flower (recessive- aa), the resulting offspring will all have heterozygous flowers (Aa) and pink (blended), instead of showing dominant trait (red).

Answer:
B
Explanation:
It would not be D because D is the location of a common ancestor, AKA an animal that does not haver jaws or bones. It would not be C because the question states that the fish has jaws, and C does not have jaws since the arrow does not point to that. It would not be A because the question states the fish has "NO TRUE BONES", meaning that there are no bones present. And in A, there is the bones arrow pointing to it, meaning that A has bones since that trait is on the same horizontal line as A. Only leaving us with option B left, since it came from an ancestor with jaws but not from an ancestor with bones. Sorry, I'm not the best with explaining but hopefully that makes sense why it is B, it's like a family tree, you just have to follow it carefully :) I hope that helps
