Concept:Self-pollination of the F1 generation produces offspring whose genotypic ratio follows Mendel’s monohybrid cross pattern.Explanation:The F1 generation from a monohybrid cross is usually heterozygous, for example Tt.When the F1 generation self-pollinates, the cross is Tt×Tt.The possible gametes are T and t from each parent.Fertilisation gives the genotypes: TT, Tt, Tt, and tt.Therefore, the genotypic ratio is 1:2:1.
