    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)

    In this scenario, let's define the alleles:
- Let **L** represent the allele for a long tail (dominant).
- Let **l** represent the allele for a short tail (recessive).
The heterozygous long-tailed mouse would have the genotype **Ll**, while the short-tailed mouse would have the genotype **ll**.
When these two mice mate, the possible genotypes of their offspring would be:
- **L** (from the heterozygous parent) and **l** (from the short-tailed parent) → **Ll** (long tail)
- **l** (from the heterozygous parent) and **l** (from the short-tailed parent) → **ll** (short tail)
The Punnett square for this cross looks like this:
| | L | l |
|-----|-----|-----|
| l | Ll | ll |
| l | Ll | ll |
From this, we see that there are 2 long-tailed offspring (**Ll**) and 2 short-tailed offspring (**ll**).
So, the chances of having offspring with short tails are **50%**.
    
- Let **L** represent the allele for a long tail (dominant).
- Let **l** represent the allele for a short tail (recessive).
The heterozygous long-tailed mouse would have the genotype **Ll**, while the short-tailed mouse would have the genotype **ll**.
When these two mice mate, the possible genotypes of their offspring would be:
- **L** (from the heterozygous parent) and **l** (from the short-tailed parent) → **Ll** (long tail)
- **l** (from the heterozygous parent) and **l** (from the short-tailed parent) → **ll** (short tail)
The Punnett square for this cross looks like this:
| | L | l |
|-----|-----|-----|
| l | Ll | ll |
| l | Ll | ll |
From this, we see that there are 2 long-tailed offspring (**Ll**) and 2 short-tailed offspring (**ll**).
So, the chances of having offspring with short tails are **50%**.
