Solution

The correct option is C The F $_{1}$ hybrid with a double recessive genotype
A test cross is a test used to determine the genotype of an organism showing dominant phenotype. It was introduced by Gregor Mendel. In this, the F $_{1}$ hybrid is crossed with a parent having double recessive genotype. If the unknown genotype is heterozygous, the recessive trait will be present in half of the offspring. However, if the unknown genotype is homozygous, the dominant trait will be present in all the offspring.
Thus, the correct answer is option C.
