What is test cross ? How can it decipher the heterozygosity of a plant ?

Answer: A test cross is a straightforward way for determining if the dominant individual’s genotype is homozygous or heterozygous in the F1 generation. If 50 percent of progeny have a dominant characteristic and 50 percent have a recessive trait after crossing with a recessive parent, the plant is said to be heterozygous.
