What does P1 generation refer to in genetics?

The P1 generation, often referred to simply as the parental generation, is the initial group of organisms from which offspring are derived in a genetic cross. This generation is significant in genetics because it establishes the baseline characteristics that will be passed down to subsequent generations. The P1 generation typically consists of purebred organisms or individuals with known traits, and the traits exhibited by these parents can be observed in the first generation of offspring, known as the F1 generation. Understanding the P1 generation is crucial for studying heredity and the inheritance of traits, as it provides insight into how genetic information flows from parents to children.
