You have carried out the test cross above and get four phenotypes of cats with the following numbers: 95 105 23 27 Somehow, you forgot to note which phenotypes went with which numbers. But, given the information above, you can figure it out. Assuming the gene that controls paw color is gene P and the gene that controls fur length is gene L (with P and L being white paws and short fur), which of the following numbers could be associated with the PL gamete (cats with white paws and short fur)?

### Genetic Analysis of Cat Phenotypes

In this exercise, you have conducted a test cross resulting in four distinct cat phenotypes. The numbers of each phenotype observed are as follows:

- 95
- 105
- 23
- 27

Unfortunately, the specific phenotypes corresponding to these numbers were not recorded. However, using the provided genetic information, we can deduce the likely associations.

#### Genetic Background:

- **Gene P**: Controls paw color; P indicates white paws.
- **Gene L**: Controls fur length; L indicates short fur.

**Objective**: Determine which number corresponds to the phenotype of cats with white paws and short fur (PL gamete).

#### Deduction Strategy:

1. **Majority Phenotypes (95 and 105)**: These larger numbers likely represent the common phenotypes resulting from dominant traits or a combination that is frequent in the test cross.
  
2. **Recombinant Phenotypes (23 and 27)**: These smaller numbers likely represent the less common phenotypes, possibly due to recombination events.

Based on genetic expectations, the PL gamete (white paws and short fur) typically aligns with one of the majority groups unless evidence indicates otherwise. However, given possible recombination, examine the alignment carefully in the context of known inheritance patterns. 

In conclusion, evaluate which numbers logically connect to the PL genotype, considering inheritance patterns and frequency of expression.
