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 F1 offspring have red eyes. The researcher then crosses two of the F1 red-eyed flies and obtains the following results in the F2 generation: Results of Eye Color Experiment
Phenotype Number of Flies in F2 Generation
Red Eyes 37
Brown Eyes 14

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.
