A cross between an F1 hybrid (Tt) and its homozygous recessive parent (tt) is specifically called a:
Show answer and explanation
Correct answer: Test cross
While it is a type of back cross, crossing a hybrid with the recessive parent is specifically a test cross. It yields a 1:1 phenotypic ratio if the hybrid is indeed heterozygous.
