1.	In cattle, the coat colour red and white are two dominant traits, which express equally F1 to produce roan ( red and white colour in equal proportion). If F1 progeny are selfbred, the resulting progency in F2 will have phenotypic ration (red : roan: white) is – (A) 1: 1:1 (B) 3 : 9 : 3 (C) 1 : 2 : 1 (D) 3 : 9 : 4
Answer» Correct Option :- (C) 1 : 2 : 1 Explanation :- This is an example of Co-dominance. (Result is 1 Red: 2 Roan: 1 white)
