Explain the statement.Test cross is a back cross but back cross is not necessarily a test cross. 

Answer»

Test cross is a back cross but back cross is not necessarily a test cross.

It is because; in back cross F1 generation can be crossed with either dominant or recessive parent. But in test cross, F1 generation is crossed with recessive parent only. Thus, test cross is a back cross but back cross is not necessarily a test cross.
