Final answer:
Two organisms with similar amino acid sequences are more likely to be related because this suggests a closer genetic and evolutionary connection.
Step-by-step explanation:
If two organisms have many of the same amino acid sequences, they would be more related to each other. Amino acid sequences are determined by the genetic code, so the more similar the sequences between two organisms, the more likely it is that they have a recent common ancestor. Therefore, the high degree of similarity in amino acid sequences suggests a closer evolutionary relationship.
