Match the following (w.r.t. pedigree analysis)
`{:(" Column - I"," Column _ II"),("a. Solid symbol"," i) Carrier of sex linked trait"),("b. Horizontal line"," ii) Offspimg between symbols"),("c. Horizontal line"," iii) Trait to be above the symbols studied"),("d. Dot in centre"," iv) Parents"):}`

Options

A. `{:(a,b,c,d),(iv,iii,ii,i):}`
B. `{:(a,b,c,d),(ii,iii,iv,i):}`
C. `{:(a,b,c,d),(iii,iv,ii,i):}`
D. `{:(a,b,c,d),(i,ii,iv,iii):}`

Answer

To solve the matching question regarding pedigree analysis, we need to understand the meanings of the symbols and lines used in pedigree charts. Let's break it down step by step:

### Step-by-Step Solution:

1. **Understanding Solid Symbol**:
- A solid symbol in a pedigree chart indicates that the individual is affected by the trait being studied. In the context of the given options, this corresponds to the trait being present in the individual.
- **Match**: A (Solid symbol) → iii (Trait to be above the symbols studied).

2. **Understanding Horizontal Line**:
- A horizontal line between two symbols represents a marriage or union between two individuals (parents). This line connects the parents to their offspring.
- **Match**: B (Horizontal line) → iv (Parents).

3. **Understanding Horizontal Line (again)**:
- The question has two instances of "Horizontal line". Since the first one is already matched with parents, the second instance can be interpreted as indicating offspring. However, since it is the same symbol, we can still associate it with the same meaning.
- **Match**: C (Horizontal line) → ii (Offspring between symbols).

4. **Understanding Dot in Centre**:
- A dot in the center of a symbol indicates that the individual is a carrier of a sex-linked trait but is not affected by it. This is typically used for individuals who carry a recessive trait.
- **Match**: D (Dot in centre) → i (Carrier of sex-linked trait).

### Final Matches:
- A → iii (Trait to be above the symbols studied)
- B → iv (Parents)
- C → ii (Offspring between symbols)
- D → i (Carrier of sex-linked trait)

### Summary of Matches:
- A - iii
- B - iv
- C - ii
- D - i
