True. Mendel studied hybrids by cross-fertilizing pea plants.
<h3>Mendel's experiment</h3>
Mendel performed several experiments to study how traits are inherited in living organisms. He used the pea plant as the reference organism.
Mendel was able to make several discoveries as far as trait inheritance is concerned. His works led to the law of inheritance - the law of segregation and the law of independent assortment of genes.
Mendel was able to achieve all these by carrying out cross-fertilization of pea plants based on different traits. For example, a pea plant that is true-breeding for wrinkle seeds was crossed with another pea plant that is true-breeding for smooth seeds.
