Correct Answer: Option C
Explanation:
In this cross, you are breeding a heterozygous tall (Tt) plant with a homozygous short (tt) plant.
The Tt plant can contribute either a T (tall allele) or a t (short allele).
The tt plant can only contribute a t allele.
The possible offspring combinations would be:
Tt (tall) from T (from the tall parent) and t (from the short parent)
tt (short) from t (from both parents)
So, the offspring will be 1 tall (Tt) for every 1 short (tt), giving a 1:1 ratio.
