1.	I = Inflated, i = constricted. Given that the phenotype of F1 progeny is inflated pods and that the parents are true-breeding, which of the following is not a possible genotype of parents?(a) Parent 1: II; Parent 2: ii(b) Parent 1: II; Parent 2: II(c) Parent 1: ii; Parent 2: ii(d) Parent 1: ii; Parent 2: IIThis question was addressed to me in quiz.This intriguing question originated from Inheritance of One Gene-1 topic in portion Principles of Inheritance and Variation of Biology – Class 12
Answer» The correct answer is (c) PARENT 1: ii; Parent 2: ii The explanation is: INFLATED is the dominant phenotype. Hence it can be EXPRESSED in two genotypes: II and Ii. The F1 progeny can have it in all the mentioned CASES except when both parents are recessive ii.
