    To solve this problem using a Punnett square, we first need to define the genotypes of the parent plants:
- Let's denote tall (dominant) as "T" and short (recessive) as "t."
- The short pea plant's genotype is "tt."
- The tall, heterozygous pea plant's genotype is "Tt."
Now we can set up the Punnett square:
```
T | t
-------------------
t | Tt | tt
-------------------
t | Tt | tt
```
From the Punnett square, we can see the following outcomes:
- 50% Tt (tall)
- 50% tt (short)
Therefore, the probability of short offspring (tt) is **50%**.
The correct answer is: **50%.**
    
- Let's denote tall (dominant) as "T" and short (recessive) as "t."
- The short pea plant's genotype is "tt."
- The tall, heterozygous pea plant's genotype is "Tt."
Now we can set up the Punnett square:
```
T | t
-------------------
t | Tt | tt
-------------------
t | Tt | tt
```
From the Punnett square, we can see the following outcomes:
- 50% Tt (tall)
- 50% tt (short)
Therefore, the probability of short offspring (tt) is **50%**.
The correct answer is: **50%.**

    The correct answer is: **codominance and multiple alleles.**
Human blood types exhibit codominance (where both alleles in a heterozygote are fully expressed, such as in type AB blood) and are also an example of multiple alleles since there are three alleles (A, B, and O) that determine blood type.
