Question

a lab technician analyzes samples for their genetic similarity. genetic dendrogram a dendrogram shows the statistical similarity between samples. in the example, a and b are 0.8 (or 80%) similar to each other but only 0.2 (20%) similar to c. a, b, and c are all 0.0 (0%) similar to d. a2 is most similar to: a. a1. b. a3 only. c. a3 and a4. d. a5, a6, a7, and a8.

Explanation:

Step1: Analyze the dendrogram

In a dendrogram, the closer two samples are joined, the more similar they are.

Step2: Locate A2

Find A2 on the dendrogram and see which sample(s) it is closest to. We can observe that A2 is joined with A3 and A4 at a relatively low - similarity distance compared to other samples.

Answer:

C. A3 and A4
