To solve this question, let's clarify the traits and symbols first:
1. **Tall (T) vs. Short (t)**: The tall trait (T) is dominant over the short trait (t).
2. **Purple (P) vs. Pink (p)**: The purple flower trait (P) is dominant over the pink flower trait (p).
Now, you're crossing two pairs of plants:
1. Homozygous dominant tall (TT) and homozygous recessive pink (pp)
2. Homozygous recessive short (tt) and homozygous dominant purple (PP)
Let's examine the two crosses separately:
### Cross 1: TT (Tall, Purple) x pp (Short, Pink)
- TT produces gametes: T
- pp produces gametes: p
The possible offspring genotypes from this cross would be:
- T from TT and p from pp → All offspring will be TtPp (tall and purple)
**Percentage of short and pink offspring:** **0%**
### Cross 2: tt (short, purple) x PP (tall, purple)
- tt produces gametes: t
- PP produces gametes: P
The possible offspring genotypes from this cross would be:
- t from tt and P from PP → All offspring will be TtPp (tall and purple)
**Percentage of short and pink offspring:** **0%**
### Final Answer
In both crosses, there can be **0% chance** of getting offspring that are short and pink. Thus, in any combination of these crosses, there are no offspring that will be short and pink.
1. **Tall (T) vs. Short (t)**: The tall trait (T) is dominant over the short trait (t).
2. **Purple (P) vs. Pink (p)**: The purple flower trait (P) is dominant over the pink flower trait (p).
Now, you're crossing two pairs of plants:
1. Homozygous dominant tall (TT) and homozygous recessive pink (pp)
2. Homozygous recessive short (tt) and homozygous dominant purple (PP)
Let's examine the two crosses separately:

- pp produces gametes: p
The possible offspring genotypes from this cross would be:
- T from TT and p from pp → All offspring will be TtPp (tall and purple)
**Percentage of short and pink offspring:** **0%**
### Cross 2: tt (short, purple) x PP (tall, purple)
- tt produces gametes: t
- PP produces gametes: P
The possible offspring genotypes from this cross would be:
- t from tt and P from PP → All offspring will be TtPp (tall and purple)
**Percentage of short and pink offspring:** **0%**
### Final Answer
In both crosses, there can be **0% chance** of getting offspring that are short and pink. Thus, in any combination of these crosses, there are no offspring that will be short and pink.
