    If a long-tailed mouse that is heterozygous (Ll) mates with a short-tailed mouse (ll), the possible genotypes of the offspring are:
- Ll (long tail)
- ll (short tail)
The offspring will have a 50% chance of having short tails. Therefore, the answer is **50%**.
    
- Ll (long tail)
- ll (short tail)
The offspring will have a 50% chance of having short tails. Therefore, the answer is **50%**.
