Tall pea plant was crossed to dwarf plant. The frequency of dwarf plants in F2 will be 0%.
A true breeding pea plant is one that, after self-fertilization, only bears offspring with the same traits.
True breeding organisms are those that share the same genes for the desired traits and are genetically comparable.
These animals possess homozygous alleles. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be expressed.
The other allele, referred to as the recessive one, has no effect.
