Foundations of genetics: On which plant did Gregor Mendel perform his classical inheritance experiments? Context: Choice of species enabled controlled crosses and clear contrasting traits. Choose the correct species.

Given data

• Mendel's classic crosses involved a garden plant with clear traits.

ApproachPisum sativum (garden pea) offered short generation time, many seeds, controlled selfing/outcrossing, and distinct contrasting traits (e.g., seed shape, flower color), making it ideal.

Final AnswerPisum sativum (garden pea).
