Use the paragraph and table to answer the question. A researcher studying fruit flies finds a fly with brown-colored eyes. Almost all fruit flies in nature have bright red eyes. When the researcher crosses the brown-eyed fly with a red-eyed fly, all of the $F_{1}$ offspring have red eyes. The researcher then crosses two of the $F_{1}$ red-eyed files and obtains the following results in the $F_{2}$ generation. $$ \begin{matrix} \text{ } & \text{Results of Eye Color Experiment} & \text{ }\\ \text{Phenotype} & \text{Number of Flies in} F_2 \text{Generation}\\ \text{Red Eyes} & \text{37}\\ \text{Brown Eyes} & \text{14}\\ \end{matrix} $$ Based on the information in this table, how would you describe the pattern of inheritance for brown-and red-colored eyes in fruit flies? Cite data from the researcher's experiments to support your description.
