Which is correct?

Options

A. Each back cross is test cross
B. Each test cross is back cross
C. Crossing `F_(2)` with `F_(1)` is called test cross
D. Crossing `F_(2)` with either parent is called test cross

Answer

B

Explanation

• The cross of `F_(1)` or `F_(2)` hybrid progeny with any of the parent is called back cross.
• If the hybrid progeny is crossed with homozygous recessive parent it is called test cross and when it is crossed with homozygous dominant parent it is called outcross. So, each test cross is back cross but each back cross is not test cross.
