Question

Give the example of back cross and Test cross ?
​

Answer 1

back cross

The cross between first filial heterozygote tall (Tt) pea plant and pure tall (TT) or pure dwarf (tt) pea plant of the parental generation is also an example for the back-crossing between two plants

test cross

Example: ... The white flower must be homozygous for the recessive allele, but the genotype of the violet flower is unknown.

Answer 2

Breeding of the dominant phenotype with the homozygous recessive phenotype (parent) is known as a test cross.

The breeding of F1 generation with one of its parent plants is known as a back cross. All test crosses are backcrosses. A backcross can be said as a test cross if the parent is recessive.
