Ah, that question still gives me shivers! I mixed them up in my board exams because I kept thinking a test cross was when you breed back to a parent like a *kazar* returning to the mother's house—total *bhon*! A test cross is with a recessive parent to check genotypes, while a back cross is to a parent to keep traits. They should've used pots! I'd remember if they said test cross is checking a mystery glaze, and back cross is going back to your reliable clay recipe.
