A group of students performed crosses between 10 garden flowers with red flowers and 10 garden flowers with blue flowers. They collected 100 healthy seeds of the f1 (first) generation and grew them. They provided equal amounts of water and sunlight to all the
plants. During the flowering season, the students observed that all of the plants had purple flowers.
Based on the results for the student's experiment, what can the students determine is most likely true about the inheritance of flower
color in these garden flowers?
