When a pure red-flowered $(RR)$ snapdragon plant is crossed with a pure white-flowered $(rr)$ plant,the $F_1$ generation produces pink flowers. When this $F_1$ progeny is self-pollinated,the resulting $F_2$ generation ratio is $1$ $(RR)$ red : $2$ $(Rr)$ pink : $1$ $(rr)$ white. This phenomenon can be explained by:

  • A
    Complete dominance
  • B
    Incomplete dominance
  • C
    Lethal genes
  • D
