F stands for

F stands for

• A. Parental
• B. Offspring
• C. First filial
• D. Genotype

Answer: (C)

In genetics, generations are labeled to track inheritance: P is the parental generation, and F stands for filial, from the Latin word for offspring. The first filial generation, F1, is the direct offspring of the parental generation. So F denotes filial, with the qualifier “first” used when referring to the F1 generation. This is why the best description is “First filial.” The term relates to generation labeling, not the organism’s genotype, and it isn’t simply “offspring” in isolation or “parental.”
