What is the Difference Between Punnett Square and Pedigree?
🆚 Go to Comparative Table 🆚Punnett squares and pedigrees are both tools used to determine the probability of inheriting a particular trait or gene, but they differ in their purpose, structure, and the information they provide.
Punnett Square:
- Represents the cross between two parents, either monohybrid or dihybrid.
- Shows all possible genotypes of a particular cross or breeding experiment.
- Used to predict the genotypes resulting from a cross.
- Does not show actual offspring.
Pedigree:
- Represents generations of a human family, typically three or more generations.
- Allows individuals to visualize patterns of inheritance throughout their family history.
- Used to trace the inheritance pattern of genetic diseases through a family.
- Utilizes symbols to denote individuals in a family, with squares representing males and circles representing females.
In summary, a Punnett square is a graphical representation of the possible genotypes resulting from a cross, while a pedigree is a chart that shows the inheritance pattern of a trait (gene) in a family over multiple generations.

Comparative Table: Punnett Square vs Pedigree
Here is a table comparing the differences between Punnett Squares and Pedigrees:
Feature | Punnett Square | Pedigree |
---|---|---|
Definition | A square diagram that shows all possible genotypes of a particular cross or breeding experiment. | A chart that shows the inheritance pattern of a trait (gene) in three or more generations of a family. |
Purpose | Represents a cross, either a monohybrid or dihybrid cross. | Represents generations of a human family, especially three or more generations of the same family. |
Genotypes | Displays all possible genotypes of a cross. | Shows the inheritance pattern of genetic diseases through a family. |
Inheritance | Helps to determine the probability of inheriting a particular trait to offspring. | Helps to trace the inheritance pattern of a trait (gene) in three or more generations. |
Visual Format | Graphical representation of possible outcomes of a cross. | Visual representation of a family's inheritance pattern. |
Both Punnett Squares and Pedigrees are tools that help determine the probability of inheriting a particular trait to offspring and predict patterns of inheritance in family lines.
