A pure breeding tall pea plant was crossed to dwarf plant. What will be frequency of dwarf plants in F2?
Temka [501]

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.

According to the given cross:

                                  TT  X  tt   (parents)

                                 Tt Tt Tt Tt  (offspring) all tall

Hence the percentage of dwarf individuals is 0.
