Question

Complete the Punnett Square to represent the cross between a heterozygous short fur cat and a long furred cat

Place only one label in each box.

You may use each label more than once.

You do not need to use all the labels.

There may be more than one correct answer.

Answer 1

To create a Punnett square for the cross between a heterozygous short fur cat (S/s) and a long furred cat (s/s), we need to represent the alleles.

Let's assume:
- **S** = Short fur (dominant)
- **s** = Long fur (recessive)

The heterozygous short fur cat has the genotype **S/s** and the long furred cat has the genotype **s/s**.

The Punnett square would be organized like this:

```
s s
+-----+-----+
S | S/s | S/s |
+-----+-----+
s | s/s | s/s |
+-----+-----+
```

Now we fill in the boxes:
- Top row: Alleles from the heterozygous short fur cat (S, s)
- Side column: Alleles from the long furred cat (s, s)

Now we fill in the individual boxes with the resulting genotypes:

- First box (S/s) → Short fur
- Second box (S/s) → Short fur
- Third box (s/s) → Long fur
- Fourth box (s/s) → Long fur

Therefore, the complete Punnett Square with labels would be:

```
s s
+-------+-------+
S | Short | Short |
+-------+-------+
s | Long | Long |
+-------+-------+
```

Labels for the boxes:
1. Short
2. Short
3. Long
4. Long

So the Punnett square clearly shows that there is a 50% chance of having short fur cats (S/s) and a 50% chance of having long fur cats (s/s).
