In genetics, "B" typically represents a dominant allele (brown eyes), and "b" represents a recessive allele (blue eyes).
Let's break down the cross:
- The heterozygous brown-eyed individual has the genotype **Bb**.
- The homozygous blue-eyed individual has the genotype **bb**.
When these two individuals are crossed, we can set up a Punnett square to determine the possible genotypes of the offspring:
```
B b
----------------
b | Bb | bb |
----------------
b | Bb | bb |
----------------
```
From this Punnett square, we can see the possible offspring genotypes are:
- **Bb**: brown eyes (2 out of 4, or 50%)
- **bb**: blue eyes (2 out of 4, or 50%)
Thus, 50% of the offspring will have brown eyes.
