Solution

The correct option is C Assertion is correct but Reason is incorrect
In F2 generation both the parental traits of a character are expressed in the ratio of three dominant to one recessive. In F1 generation only one of the parental traits is expressed and the other lies hidden or unexpressed. However, there is no mixing of two characters in the hybrid. At the time of gamete formation, two factors separate or segregate and pass into different gametes which hence have one factor of a pair. During fertilisation, gametes fuse randomly so that factors come together in new generation and express themselves freely. So, the correct answer is 'Assertion is correct but Reason is incorrect'.
