The generation that results from crossing the first set of parents is called what?

The generation that results from crossing the first set of parents is called what?

• A. P generation
• B. F1 generation
• C. F2 generation
• D. G2 generation

Answer: (B)

In genetics, generations are named to trace how traits pass from one set of organisms to the next. The parents used in a cross are called the parental or P generation, and the offspring produced directly from that cross are the first filial generation, abbreviated F1. These F1 offspring are the immediate hybrids formed by combining the parental alleles. If you crossed two F1 individuals, you’d get the F2 generation. So, the generation that results from crossing the first set of parents is the F1 generation.
