Answer

Brief Explanations:

When a cross between a homozygous dominant (TT) and a homozygous recessive (tt) occurs, all offspring will be heterozygous (Tt). In the cross Tt x tt, half of the offspring will be heterozygous. In Tt x Tt, the offspring have different genotypes including homozygous and heterozygous in a ratio. In tt x tt, all offspring are homozygous recessive.

Answer:

D. TT x tt
