Solution :-

A cross between a plant with unknown genotype and the recessive parent is called as a test cross.

A test cross is used to determine the genotype of the unknown plant (i.e whether the plant is homozygous or heterozygous). If the progeny of the test cross show 1:1 ratio of Dominant: Recessive, then the unknown plant is heterozygous. However, if the progeny are all dominant, then the unknown plant is homozygous.
