Question

Define the term F₁ generation.

Answer 1

F1

1. It stands for Filial 1, the first filial generation seeds/plants or animal offspring resulting from a cross-mating of distinctly different parental types.
2. The term F₁ generation refers to the first filial generation of offspring produced by crossing a set of parents.
3. The ‘F’ in F₁ stands for ‘filial, which refers to the subsequent sets of offspring produced from a controlled or observed reproduction.

For example: When parents with genotype RRYY-round & yellow seed and rryy- wrinkled & green seed are crossed in the F₁ generation, we get the heterozygous round and yellow seed plants with genotype RrYy.
