Type of Inheritance Examples A. Incomplete dominance 1. Flower color in snapdragon B. Codominance 2. ABO blood group in humans C. Multiple alleles 3. Coat color in cattle D. Polygenic inheritance 4. Skin color in humans

Options

  1. AA - 3, B - 2, C - 1, D - 4
  2. BA - 4, B - 1, C - 2, D - 3
  3. CA - 1, B - 3, C - 2, D - 4
  4. DA - 2, B - 4, C - 3, D - 1

Correct answer

C. A - 1, B - 3, C - 2, D - 4

Step-by-step solution

Incomplete dominance: Flower color in snapdragon (red and white produce pink offspring). Codominance: Coat color in cattle (both black and white colors appear together). Multiple alleles: ABO blood group system in humans. Polygenic inheritance: Skin color in humans is controlled by multiple genes.
