According to Mendel's Law of Segregation, one individual out of four in the F2 generation had a phenotype that failed to express in the generation.
Correct answer: A. F1
- A. F1
- B. F2
- C. F3
- D. P1
Explanation
F1: Correct, as the F1 generation refers to the first filial generation produced by crossing two parents. According to Mendel's Law of Segregation, all F1 offspring will express the dominant phenotype, and the recessive trait is not expressed in this generation. It is only in the F2 generation (the second filial generation) that the recessive phenotype can reappear, but the question is about the F1 generation, where the recessive phenotype is hidden.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
