Answer

Answer:

D. TT × tt

Brief Explanations:

When a homozygous dominant (TT) and a homozygous recessive (tt) parent cross, all offspring will be heterozygous (Tt). In the other options, such a 100% heterozygous - offspring outcome is not guaranteed. For example, in Tt × Tt, there will be homozygous and heterozygous offspring, in Tt × tt there will be a mix of heterozygous and homozygous recessive offspring, and in tt × tt all offspring will be homozygous recessive.
