Answer :
In this scenario, we have a cross between a heterozygous striped tabby cat (Ss) and a solid colored cat (ss).
1. Genotypic ratio:
- The possible genotypes of the offspring are SS, Ss, and ss.
- When a heterozygous striped tabby cat (Ss) is crossed with a solid colored cat (ss), the Punnett square would look like this:
```
| S | s |
-----------------
S | SS | Ss |
-----------------
s | Ss | ss |
```
- Therefore, the genotypic ratio would be 1:2:1 for SS:Ss:ss.
2. Phenotypic ratio:
- The dominant allele (S) for stripes will result in striped coat color, while the recessive allele (s) will give a solid coat color.
- As per the Punnett square, the possible phenotypes of the offspring would be striped and solid colored cats.
- Hence, the phenotypic ratio would be 3 (striped):1 (solid).
In summary, when a heterozygous striped tabby cat is crossed with a solid colored cat, the expected genotypic ratio of the offspring would be 1:2:1 for SS:Ss:ss, and the phenotypic ratio would be 3 (striped):1 (solid).
