Answer:
The law of segregation states that during the formation of gametes (sex cells), the alleles (different forms of a gene) for a particular trait separate and are passed on independently to each offspring.
In the F1 generation, which is the first filial generation, the law of segregation applies as the alleles for a particular trait separate during meiosis and are passed on to the gametes. These gametes are then combined during fertilization to form the F1 offspring.
In the F2 generation, which is the second filial generation, the law of segregation applies again as the F1 individuals produce gametes through meiosis, and the alleles for a particular trait separate and are passed on independently to the F2 offspring. As a result, the F2 generation will exhibit Mendel's ratios of inheritance for that trait.
In summary, the law of segregation applies to both the F1 and F2 generations as it ensures that the alleles for a particular trait are passed on independently during meiosis, and Mendel's ratios of inheritance are observed in the F2 generation.
