The F generation refers to the offspring of the

• A. Parental generation
• B. Offspring of P
• C. First filial offspring
• D. Hybrid

Answer: (C)

In genetics, generation labels track how traits pass from parents to offspring, with F standing for filial. The F generation represents the offspring produced from crossing the parental generation. The first filial generation, abbreviated F1, are the direct offspring of the true-breeding P (parental) lines and are typically hybrids between those parental varieties. After crossing F1 individuals, you get the second filial generation, F2, and so on. So the F generation is best described as the First filial offspring—the direct offspring of the parental generation. While F1 individuals can be hybrids, the precise term here emphasizes their place in the generational sequence rather than just their mixed ancestry.
