Question
### SNP and BMI Correlation Analysis

#### BMI Definition:
- Body Mass Index (BMI) is the ratio of mass in kilograms to the square of height in meters. A BMI between 18 and 25 is considered normal. Below 18 is considered low, and above 25 is high.

#### Objective:
To find Single Nucleotide Polymorphisms (SNPs) that correlate with low BMI.

#### Data Table:
| BMI | SNP1 | SNP2 | SNP3 | SNP4 |
|-----|------|------|------|------|
| 25  | A    | G    | T    | A    |
| 16  | A    | G    | T    | C    |
| 31  | A    | G    | T    | A    |
| 15  | A    | C    | C    | C    |
| 26  | T    | C    | C    | A    |

**Question:** Identify the SNP that best correlates with low BMI.

### Exome Sequencing

#### Definition:
Exome sequencing is a genomic technique for sequencing all of the protein-coding regions of genes in a genome, known as the exome.

#### Application:
One of the key applications is identifying genetic mutations that lead to diseases.

### Genetic Pedigree Analysis

#### Description:
The given pedigree represents an autosomal dominant trait. The goal is to identify the gene responsible by examining variable markers to find associations near the disease gene.

#### Pedigree Diagram:
- Circles represent females, squares represent males.
- Filled symbols indicate individuals with the trait.

#### Genetic Marker Table:
| Individual | A  | B  | C  | D  | E  | F  |
|------------|----|----|----|----|----|----|
| 1-1        | 2  | 3  | 1,5| 1,6| 3,7| 2,9|
| **1-2**    | 3  | 7  | 2,6| 4,5| 4,8| 4,7|
| 2-1        | 4,5| 2,6| 3,7| 8,9| 2,6| 1,3|
| **2-2**    | 3  | 3,6|
