The second filial generation is:

The second filial generation is:

• A. First filial generation from self-pollination
• B. Offspring of two parental lines
• C. Second filial generation from self-pollinating F1
• D. Offspring produced by crossing two P generation

Answer: (C)

The second filial generation is the offspring produced when the first filial generation (the hybrids from crossing true-breeding parents) is self-pollinated. In other words, F2 comes from selfing F1 or crossing two F1 individuals, which reveals the segregation of alleles Mendel described. The other scenarios describe the first filial generation (offspring of two parental lines or crossing two P lines) or selfing of the P generation, not the F2.
