An understanding of Mendel's pea plant experiment and its consequences. An understanding of the difference between dominant and recessive genes and their relationship to incomplete dominance. An understanding of the inheritance of genes, including the laws of segregation and independent assortment. Understanding the difference between pure-breds and hybrids. Mendel's Pea experiment.
Pea plants grow and reproduce quickly.
They have a wide variety of different traits , and were easy to breed and cross-pollinate. Mendel called these plants true-breeding plants, plants that always produce offspring with the same traits as their parents. Mendel realized that each plant must contain two factors for a particular trait. He called these factors genes . He called the weaker trait which did not appear in those offspring recessive .
