Difference between Test Cross and Backcross
• All test crosses are considered as backcrosses, but all backcrosses are not the test crosses.
• During backcross, F1 hybrid is crossed back with any of the parents, eit her homozygous or heterozygous. However, during test cross, F 1 hybrid is always crossed back with the recessive parent.
