The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding Alleles**: An allele is defined as a variant form of a gene. Each gene can have multiple alleles, which are different versions of that gene. 2. **Examples of Alleles**: For instance, consider the gene that determines height in plants or animals. This gene can have two main variants: one that is dominant and another that is recessive. 3. **Notation of Alleles**: The dominant allele is typically represented by a capital letter (e.g., T for tall), while the recessive allele is represented by a lowercase letter (e.g., t for short). 4. **Pairing of Alleles**: Alleles come in pairs, one inherited from each parent. Therefore, for the height gene, an individual could have two dominant alleles (TT), two recessive alleles (tt), or one of each (Tt). 5. **Conclusion**: Based on the definition and examples, the correct answer to the question "Alleles are" is option B: "pair of genes governing a specific character like height."
