What does the P generation refer to in genetics?

  1. Offspring of the F1 generation

  2. Parental generation

  3. Offspring of the P generation

  4. Gametes produced

The correct answer is: Parental generation

The P generation refers specifically to the parental generation in genetics. This is the first set of individuals that are crossed in a genetic study, and their offspring are referred to as the F1 generation. The P generation serves as the foundational reference for subsequent generations in experiments, particularly those related to Mendelian inheritance. By examining the traits of the P generation, researchers can establish patterns of inheritance and predict the traits of offspring based on the genetic makeup of the parents. This understanding is critical in studying inheritance patterns, genetic traits, and the principles of dominance and recessiveness.
