Options

A. a-(ii), b-(i), c-(iv), d-(iii)
B. a-(ii), b-(i), c-(iii), d-(iv)
C. a-(iv), b-(i), c-(iii), d-(ii)
D. a-(i), b-(ii), c-(iii), d-(iv)

Answer

To solve the matching question between Column I and Column II, we will analyze each term in Column I and find the correct match from Column II based on the information provided in the video transcript.

### Step-by-Step Solution:

1. **Match Phenotype**:
- The term "phenotype" refers to the observable characteristics of an organism, which are influenced by its genetic makeup. The term was used by **Johansson** to describe these observable traits.
- **Match**: (a) Phenotype → (ii) Johansson

2. **Match Heterozygous**:
- The term "heterozygous" describes an organism that has two different alleles for a particular gene. This term was first used by **William Bateson** to differentiate between homozygous and heterozygous conditions.
- **Match**: (b) Heterozygous → (iv) Bateson

3. **Match Heterozygous Again**:
- Since the second term is also "heterozygous", it will match with the same individual as above.
- **Match**: (c) Heterozygous → (iv) Bateson

4. **Match Incomplete Dominance**:
- Incomplete dominance is a genetic situation where neither allele is completely dominant over the other, resulting in a phenotype that is a blend of the two. This concept was discovered by **Karl Correns**.
- **Match**: (d) Incomplete dominance → (iii) Correns

### Final Matches:
- (a) Phenotype → (ii) Johansson
- (b) Heterozygous → (iv) Bateson
- (c) Heterozygous → (iv) Bateson
- (d) Incomplete dominance → (iii) Correns

### Summary of Matches:
- (a) Phenotype → (ii) Johansson
- (b) Heterozygous → (iv) Bateson
- (c) Heterozygous → (iv) Bateson
- (d) Incomplete dominance → (iii) Correns
