To solve this problem, we need to match the terms in Column I with their descriptions in Column II. Let's analyze each term:$\newline \bullet$a. Dominance:$\newline$ - In a heterozygous organism, only one allele expresses itself.$\newline$ - This matches with ii.$\newline \bullet$b. Codominance:$\newline$ - In a heterozygous organism, both alleles express themselves fully.$\newline$ - This matches with iii.$\newline \bullet$c. Pleiotropy:$\newline$ - A single gene influences the inheritance of many characters.$\newline$ - This matches with iv.$\newline \bullet$d. Polygenic:$\newline$ - Many genes govern a single character.$\newline$ - This matches with i.$\newline$Now, let's match the items from Column I with Column II:$\newline a \rightarrow ii, b \rightarrow iii, c \rightarrow iv, d \rightarrow i \newline$This corresponds to Option 2.
