A test cross is used to find out wether a given tall garden pea plant is homozygous or heterozygous

Explanation:

  • Homozygous dominant genotype is TT and homozygous recessive  
  • genotype is tt(homozygous parents)
  • the gamete is Tt,that is all tall plants,F1 generation all tall plants.F1 ratio 1:0
  • wether by Punnet square also the same genotype.
  • now the cross between hybrid dominant Tt and homozygous recessive tt ,the same thing will be observed in a Punnet square too.
  • F1 generation 1:1 ratio one tall plant and one dwarf plant
  • this cross is used to find out the genotype of unknown trait,wether it is homozygous or heterozygous dominant for the trait.
