Procedure:
- Assuming both parents carry three tall genes and three short genes, you will model the inheritance of height for ten different offspring. Flip a coin six times to determine how many tall and short genes the child inherits. Heads represents a tall gene and tails represents a short gene.
- Record all of your data along with the class data in the tables below

Penny Situation |
Height |
|
O Tails and 6 Heads |
6 feet 1 inch |
|
1 Tail and 5 Heads |
5 feet 11 inches |
|
2 Tails and 4 Heads |
5 feet 9 inches |
|
3 Tails and 3 Heads |
5 feet 7 inches |
|
4 Tails and 2 Heads |
5 feet 5 inches |
|
5 Tails and 1 Head |
5 feet 3 inches |
|
6 Tails and 0 Heads |
5 feet 1 inch |
Remember: Heads are tall genes. Tails are short genes.
- Analyze the class data and propose an explanation for an apparent trend in height.
