Mendel used pure lines in his experiments to ensure that he was studying traits that were consistently inherited and not influenced by mixed genetic backgrounds. By starting with true-breeding plants, he could accurately observe the patterns of inheritance and distinguish dominant and recessive traits. This approach allowed him to establish foundational principles of heredity, such as the laws of segregation and independent assortment.
They were homozygous.

In Mendel's experiments, pure lines refer to strains of plants that consistently produce offspring with the same traits over generations when self-fertilized. These pure lines were achieved by breeding pea plants that exhibited specific traits, such as flower color or seed shape, ensuring that the genetic makeup was uniform. Mendel used these pure lines to establish the foundational principles of inheritance, demonstrating how traits are passed from one generation to the next through dominant and recessive alleles.
Mendel used pure lines in his experiments to ensure that the traits he was studying were consistently expressed over generations. This helped him establish clear patterns of inheritance and accurately determine how traits were passed from one generation to the next.
Mendel used pure lines in his experiments to ensure that the traits he was studying were consistently expressed and not influenced by other genetic variations. By starting with true-breeding plants, he could accurately track how specific traits were inherited across generations. This allowed him to establish clear patterns of inheritance and formulate his foundational principles of genetics, such as the laws of segregation and independent assortment.

Mendel used pure lines in his experiments to ensure that the traits he was studying were consistently expressed in offspring. By starting with true-breeding plants that produced the same traits generation after generation, he could accurately track how traits were inherited. This allowed him to formulate his principles of inheritance, such as the laws of segregation and independent assortment, without the confounding effects of mixed genetic backgrounds.
Mendel developed several pure lines of peas for his experiments, primarily focusing on seven traits, including seed shape (round vs. wrinkled), seed color (yellow vs. green), pod shape (inflated vs. constricted), and flower color (purple vs. white). These pure lines were homozygous for the traits he studied, allowing him to observe the inheritance patterns when crossing different varieties. His meticulous breeding and record-keeping established foundational principles of genetics, including the concepts of dominance and segregation.
Mendel crossed a pure-breeding round-seeded variety with a pure-breeding wrinkled-seeded one. All the peas produced in the second or hybrid generation were round.
