P1 or parental
F2 generation (second filial generation)
recessive trait
The first generation of offspring in Mendel's experiments are called the F1 generation or the first filial generation. These are the offspring resulting from the crossing of two parental or P generation plants.
The first generation of offspring in Mendel's experiment were all hybrids (F1 generation), resulting from the cross of two purebred parents with contrasting traits.
P1 stands for "parental generation." This refers to the parents (mom and dad) who start off the pedigree. The P1 generation can then produce offspring (called the F1, or "first filial generation"). The F1 generation could then produce the F2 generation (or "second filial generation").

p1 or parental
The second generation of offspring from a cross of two organisms is known as the F2 generation. In this generation, the genetic traits from the original parent organisms are recombined and expressed in new combinations. The F2 generation results from the mating of two F1 individuals, which are the first generation offspring of the original parents.
The parental organisms that are crossed are typically of two different generations or lines: the P1 generation, which are the original parents, and the F1 generation, which are the offspring resulting from their cross.
