Match List I with List II : List I List II A Incomplete dominance 1 A single gene can exhibit multiple phenotypic expressions B Co-dominance 2 More than two alleles govern the same character C Pleiotropy 3 F ₁ generation resembles both the parents D Multiple alleles 4 F ₁ generation is in between the two parents Choose the correct answer from the options given below :

Step-by-step solution

Incomplete dominance occurs when the F ₁ generation has a phenotype that is intermediate between the two parents. Co-dominance occurs when the F ₁ generation resembles both parents, as both alleles express themselves fully. Pleiotropy is the phenomenon where a single gene exhibits multiple phenotypic expressions. Multiple alleles refer to the condition where more than two alleles govern the same character. Thus, the correct matching is A-4, B-3, C-1, D-2. Answer: A-4, B-3, C-1, D-2
