Answer:
D
Explanation:
He bred two true-breeding strains initially. That means the alleles were homozygous for each gene.
Let's use Tt to represent the height allele: T means tall, t means short; the dominant allele gets the capital letter.
Let's use Pp to represent the flower color allele: P means purple, p means white.
<u>A pure-breeding tall, purple plant would be </u><u>TTPP.</u>
<u>A pure-breeding short, white plant would be </u><u>ttpp.</u>
So the cross is <u>D. TTPP x ttpp.</u>
The correct answer is - ttPP × TTpp
