In genetics, the traits for eye color can often be represented using letters for the dominant and recessive alleles. In this case, "B" represents the dominant allele for brown eyes, while "b" represents the recessive allele for blue eyes.
Based on the genotypes you've provided:
- **BB**: Homozygous dominant (has brown eyes).
- **Bb**: Heterozygous (has brown eyes, since the brown allele is dominant).
- **bb**: Homozygous recessive (has blue eyes).
If you’re looking to understand how these traits might be passed on or how they combine in offspring, here’s a simple example of a Punnett square using a Bb (brown eyes) parent and a bb (blue eyes) parent:
| | **B** | **b** |
|--------|-------|-------|
| **b** | Bb | bb |
| **b** | Bb | bb |
From this cross, the possible offspring genotypes are:
- **Bb (brown eyes)**: 50%
- **bb (blue eyes)**: 50%
So, there is a 50% chance that the offspring will have brown eyes and a 50% chance for blue eyes when one parent is heterozygous (Bb) and the other is homozygous recessive (bb). If you have a specific question or scenario in mind, please let me know!
