Hello,
In test cross a dominant phenotype is crossed with recessive phenotype and in back cross crossing occurs between F1 hybrid and one of the parents. And now when you read this dinifination you will make sense that how test cross can be a back cross but a back cross can never be a test cross. You always have to involve F1 hybrid and parent in back cross hence it never is a test cross.
Thank you
