1. How can you tell if a couple is married on a pedigree?

Answer:
A couple is shown as being married on a pedigree when two individuals (one male and one female) are connected by a horizontal line between them.

Example:

```
Mary Greg
○---------□
```

- The circle (○) represents Mary (unaffected female).
- The square (□) represents Greg (unaffected male).
- The horizontal line connecting them indicates marriage.

> 🔹 Explanation: In pedigree charts, marriage is represented by a horizontal line between a male (square) and a female (circle).

2. How can you tell if the couple who is married had children?

Answer:
If a couple has children, a vertical line extends downward from the marriage line, and then individual symbols (squares or circles) for the children are drawn below it.

Example:

```
Mary Greg
○---------□
|
|
□ □ ○
Scott Tyler Karen
```

- The vertical line from the marriage line shows that they have offspring.
- The children are placed in a row beneath, with squares for males, circles for females.

> 🔹 Explanation: Children are shown directly below the parents, connected by a vertical line from the marriage line.

3. Draw a pedigree that represents Mary married to Greg and with 2 sons (Scott and Tyler) and 1 daughter (Karen). Please label the pedigree with the names of the people.

Answer (Diagram):

```
Mary Greg
○------------------□
|

□ □ ○
Scott Tyler Karen
```

Explanation:
- Mary = circle (female)
- Greg = square (male)
- Horizontal line = marriage
- Vertical line from marriage → children
- Sons (Scott, Tyler) = squares
- Daughter (Karen) = circle
- Names labeled under each symbol

> ✔ This shows the first generation (Mary & Greg) and their three children.

4. Draw a pedigree that represents Mary married to Greg, with 2 sons and 1 daughter. Their son, Scott, married April and had Sutton (a boy) and Kendall (a girl). Their daughter, Karen, married Harry and had Eliq (a son) and Tariq (a son). Please label the pedigree with the names of the people.

Answer (Diagram):

```
Mary Greg
○------------------□
|
|
□ □ ○
Scott Tyler Karen
| |

#### Generation II (Children):

| □ | Unaffected male |
| ■ | Affected male |
| ⬛ | Carrier male |
| ○ | Unaffected female |
| ● | Affected female |

Final Notes:

- Pedigrees show family relationships and inheritance patterns.
- Always draw parents above, children below, and use lines to indicate marriage and descent.
- Labeling names helps identify individuals clearly.
