symbols &&&&& and %%%%% are used to denote the female (eggs) and male (pollen) of the F generation, respectively. The F plant of the genotype Tt when self-pollinated, produces gametes of the genotype T and t in equal proportion. When fertilisation takes place, the pollen grains of genotype T have a per cent chance to pollinate eggs of the genotype T , as well as of genotype t . Also pollen grains of genotype t have a per cent chance of pollinating eggs of genotype T , as well as of Figure .
