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.
