What is one key outcome of Mendel's experiments with pea plants?

• A. The discovery of DNA
• B. The prediction of genetic disorders
• C. The establishment of dominant and recessive traits
• D. The development of hybrid plants

Answer: (C)

Mendel's experiments with pea plants laid the foundation for the understanding of inheritance and genetics. One of the key outcomes from his work was the establishment of the concepts of dominant and recessive traits. Through systematic breeding experiments, Mendel observed how traits such as flower color and seed shape were passed from one generation to the next. He identified that some traits were dominant, meaning they would be expressed in the phenotype even if only one copy was present, while others were recessive and would only be expressed if two copies were inherited. This framework of dominant and recessive traits fundamentally shaped the field of genetics, leading to the formulation of what we now know as Mendel's laws of inheritance. The other options do not accurately capture the essence of Mendel's contributions. For instance, while hybrid plants can result from his experiments, the key takeaway was not the development of hybrids but rather understanding how traits are inherited. The discovery of DNA came much later, after Mendel's time, and predicting genetic disorders was beyond the scope of his initial work.
