1.	If a cross between true-breeding red-flowered and true-breeding white-flowered plants give rise to pink-flowered progeny, what is the mode of inheritance?(a) Complete dominance(b) Incomplete dominance(c) Codominance(d) Multiple allelismThis question was posed to me during an interview.My question is from Inheritance Principles in portion Principles of Inheritance and Variation of Biology – Class 12
Answer» The correct answer is (b) Incomplete DOMINANCE For explanation I would say: Incomplete dominance involves the blending of characters in the PROGENY that are heterozygotes. Here red and white-flowered plants PRODUCE pink-flowered progeny. Hence this is an instance of incomplete dominance.
