Genetics

My father won a prize by a telecom company. He was offered 3 choices: An investment plan, a holiday for 4 to Goa and appliances from a certain electronic appliance maker for a certain amount. He has to make up his mind on Monday. Mamma called up my sister, brother and me to get a consensus. My sister said, "Appliances, of course!" My brother said, "The investment plan is the wisest decision, of course." I said, "Which fool would not choose the holiday?"

Mother still does not have a consensus.
