A scientist is trying to determine how closely related a moth species (Species Z) is to four other moth species (Species A, B, C, and D). He examined the DNA of each species and compared it to the study subject. He then created this table.

\begin{tabular}{|c|c|}
\hline Species & \# of Genetic Differences \\
\hline Species A & 12 \\
\hline Species B & 3 \\
\hline Species C & 14 \\
\hline Species D & 28 \\
\hline
\end{tabular}

Which species is most closely related to the moth species (Species Z)?

A. Species A
B. Species B
C. Species C
D. Species D

To determine which species is most closely related to Species Z, we need to find the species with the fewest genetic differences compared to Species Z. The table provided lists the number of genetic differences for each species:

[tex]\[ \begin{array}{|c|c|} \hline \text{Species} & \# \text{ of genetic differences} \\ \hline \text{Species A} & 12 \\ \hline \text{Species B} & 3 \\ \hline \text{Species C} & 14 \\ \hline \text{Species D} & 28 \\ \hline \end{array} \][/tex]

We will now identify the species with the minimum number of genetic differences.

1. Species A has 12 genetic differences.
2. Species B has 3 genetic differences.
3. Species C has 14 genetic differences.
4. Species D has 28 genetic differences.

From the given numbers, the species with the fewest genetic differences is Species B with only 3 differences. Therefore, Species B is the most closely related to Species Z.

Hence, the species most closely related to Species Z is Species B.
