Column I: (a) Dominance, (b) Codominance, (c) Pleiotropy, (d) Polygenic inheritance
Column II: (i) Many genes govern a single character, (ii) In a heterozygous organism only one allele expresses itself, (iii) In a heterozygous organism both alleles express themselves fully, (iv) A single gene influences many characters

Solution & Step-by-step Explanation

- Dominance: Only one allele expresses itself in heterozygote.Codominance: Both alleles express themselves fully (e.g., AB blood group).Pleiotropy: Single gene controls multiple phenotypic traits.Polygenic inheritance: Multiple genes control a single trait (e.g., human skin color).
