    In mice, the gene for tail length has two alleles. A long tail is dominant to a short tail. If a long-tailed mouse that is heterozygous mates with a short-tailed mouse, what are the chances of having offspring with short tails?(1 point)

    If a long-tailed mouse that is heterozygous (Ll) mates with a short-tailed mouse (ll), the possible offspring genotypes can be determined using a Punnett square:
- Ll (long-tailed) x ll (short-tailed)
  
The possible genotypes of the offspring will be:
- Ll (long tail)
- Ll (long tail)
- ll (short tail)
- ll (short tail)
This means there are 2 long-tailed offspring and 2 short-tailed offspring.
Thus, the chances of having offspring with short tails (ll) are **50%**.
    
- Ll (long-tailed) x ll (short-tailed)
The possible genotypes of the offspring will be:
- Ll (long tail)
- Ll (long tail)
- ll (short tail)
- ll (short tail)
This means there are 2 long-tailed offspring and 2 short-tailed offspring.
Thus, the chances of having offspring with short tails (ll) are **50%**.
