The process of choosing only plants and animals with desirable characteristics to reproduce
Selective breeding
Who is the founder of genetics?
Gregor Mendel

Ms. Sophia crosses the purple corn plant (hybrid) and the yellow corn plant (hybrid), and all resulting plants with 3 yellow corn plants and 1 purple corn plant. Determine which corn plant with the dominant trait.
the yellow corn plant
Ms. Sophia crosses purebred yellow rose plants with purebred red rose plants, and all the resulting plants produce yellow roses. Determine which plant with the dominant trait in this case.
