Introduction: Gregor Mendel, an Austrian monk, is known for his pioneering work in the field of genetics. He conducted a series of experiments on pea plants to understand the inheritance of certain traits. One of the experiments he performed was a monohybrid cross using the round and wrinkled seeds. In this experiment, Mendel aimed to understand the inheritance of seed shape in peas.

Main Content: Mendel performed a monohybrid cross by breeding a true-breeding pea plant that produced round seeds with another true-breeding pea plant that produced wrinkled seeds. He found that all of the offspring produced in the first generation (F1) had round seeds. However, in the second generation (F2), he observed that some of the offspring had round seeds while others had wrinkled seeds. He found that the F1 generation was 3:1 ratio of round:wrinkled. He then proposed that the characters of the traits were controlled by pairs of genes, one gene inherited from each parent, and that the dominant gene masks the recessive gene. He also proposed that the dominant gene is responsible for round seed shape and the recessive gene is responsible for wrinkled seed shape.

Conclusion: Mendel's experiment provided evidence for the inheritance of seed shape in peas and the concept of dominant and recessive genes. Additionally, Mendel's experiment laid the foundation for the study of genetics and the understanding of how traits are passed down from one generation to the next. His work continues to be an important reference for understanding the basic principles of genetics and heredity.
