Allelomorphic pair implies

Options

A. A pair of contrasting traits
B. A pair of noncontrasting traits
C. Any two traits
D. Sex-linked traits.

Answer

**Step-by-Step Solution:**

1. **Understanding Allelomorphic Pairs:**
- Allelomorphic pairs refer to pairs of alleles that represent contrasting traits for a particular characteristic.

2. **Identifying Traits:**
- A trait is a specific characteristic of an organism, such as height, color, or shape. In genetics, traits can be dominant or recessive.

3. **Contrasting Traits:**
- Contrasting traits are those that are opposite to each other. For example, in pea plants studied by Mendel, the height trait can be either tall or dwarf.

4. **Examples of Alleles:**
- For the height trait:
- Tall (dominant) can be represented by the allele "T".
- Dwarf (recessive) can be represented by the allele "t".
- For another trait, such as flower position:
- Axial position (dominant) can be represented by "A".
- Terminal position (recessive) can be represented by "a".

5. **Conclusion:**
- Since allelomorphic pairs refer specifically to pairs of contrasting traits, the correct answer to the question "Allelomorphic pair implies" is **option 1: a pair of contrasting traits**.
