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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd4250c70-101e-4757-a6ed-7ce80aa4695e%2Fc3f3ed18-0bdf-41ef-867c-c6901ce40bcf%2Fhinn2eq_processed.png&w=3840&q=75)
Transcribed Image Text:### 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 |
|---------------|----------|-----------------------|
|  | TT | 260 |
|  | Tt | 160 |
|  | tt | 80 |
