### Population Genetics of Cat Tail Length

A population of 500 cats has two alleles of interest for determining tail length. The T allele encodes for a long tail and is completely dominant over the t allele, which encodes for a short tail. The table below presents the phenotype of cats with each possible genotype as well as the number of individuals in the population with each genotype.

| Phenotype     | Genotype | Number of Individuals |
|---------------|----------|-----------------------|
| ![Long-tailed cat](https://via.placeholder.com/50) | TT       | 260                   |
| ![Long-tailed cat](https://via.placeholder.com/50) | Tt       | 160                   |
| ![Short-tailed cat](https://via.placeholder.com/50) | tt       | 80                    |

In this table:

- **Phenotype**: The observable characteristic of the cats (long-tailed or short-tailed).
- **Genotype**: The genetic makeup of the cats (TT, Tt, or tt).
- **Number of Individuals**: The count of cats having each specific genotype.

This data illustrates that:

- 260 cats possess the TT genotype and display a long-tailed phenotype.
- 160 cats possess the Tt genotype and also exhibit a long-tailed phenotype due to the dominance of the T allele.
- 80 cats possess the tt genotype, resulting in a short-tailed phenotype.

This visualization helps in understanding the distribution of alleles and corresponding phenotypes in a given population of cats.
