Correct Answer: Option E
Explanation:
The correct answer is:
E. 4 tall : 0 short
In this case, if a homozygous tall plant (TT) is crossed with a homozygous dwarf plant (tt), all offspring (F1 generation) will inherit one tall allele (T) from the tall parent and one dwarf allele (t) from the dwarf parent. Therefore, all offspring will be heterozygous tall (Tt), and the genetic ratio will be 4 tall : 0 short.
