Match the terms in Column I with their descriptions in Column II and choose the correct option.
| Column I | Column II |
|---|---|
| a. Dominance | i. Many genes govern a single character |
| b. Co-dominance | ii. In a heterozygous organism only one allele expresses itself |
| c. Pleiotropy | iii. In a heterozygous organism both alleles express themselves fully |
| d. Polygenic inheritance | iv. A single gene influences many characters |
Correct answer · Option 4
a-ii, b-iii, c-iv, d-i
Explanation
Dominance (a-ii) occurs when only one allele expresses in heterozygotes. Co-dominance (b-iii) is when both alleles express fully. Pleiotropy (c-iv) is a single gene affecting multiple traits, and Polygenic inheritance (d-i) involves multiple genes governing one character.
