Question

answer the blanks

4. SpongeBob SquarePants recently met SpongeSusie Roundpants at a dance. SpongeBob is heterozygous for his square shape, but SpongeSusie is round. Create a Punnett square to show the possibilities that would result if SpongeBob and SpongeSusie had children. HINT: Read question #2!
A. List the possible genotypes and phenotypes for their children. ___________________________
B. What are the chances of a child with a square shape? ____ out of ____ or ____%
C. What are the chances of a child with a round shape? ____ out of ____ or ____%

Answer 1

To answer the questions regarding the genetics of SpongeBob and SpongeSusie, we'll first designate the alleles:

- Let **S** represent the allele for square shape (dominant).
- Let **s** represent the allele for round shape (recessive).

Since SpongeBob is heterozygous, his genotype is **Ss**, meaning he has one square allele and one round allele. SpongeSusie, who is round, has the genotype **ss**.

Now we can set up the Punnett square:

```
S | s
----------------
s | Ss | ss |
----------------
s | Ss | ss |
```

From this Punnett square, we can see the possible offspring genotypes:

- **Ss** (Square shape): 2 occurrences
- **ss** (Round shape): 2 occurrences

A. List the possible genotypes and phenotypes for their children:
- **Genotypes:** Ss, ss
- **Phenotypes:** Square shape, Round shape

B. What are the chances of a child with a square shape (Ss)?
- 2 out of 4 or 50%

C. What are the chances of a child with a round shape (ss)?
- 2 out of 4 or 50%

So, filling in the blanks:

A. List the possible genotypes and phenotypes for their children. **Ss, ss; Square shape, Round shape**
B. What are the chances of a child with a square shape? **2 out of 4 or 50%**
C. What are the chances of a child with a round shape? **2 out of 4 or 50%**
