Study Notes
Understanding Alleles and Genotypes
- Alleles are different forms of a gene.
- Dominant alleles are represented by capital letters (e.g., B).
- Recessive alleles are represented by lower-case letters (e.g., b).
- Choose letter representations that are easily distinguishable in their upper and lower-case forms (e.g., B and b).
- Genotypes describe the combination of alleles an organism has.
- Use appropriate notation when describing alleles.
