In an experiment on Drosophila, the true breeding red eyed female is crossed with true breeding white eyed male and all the progeny of F₁ generation were red eyed. When inter crossing is done between the individuals of F₁, what is the ratio of obtaining red eyed females, red eyed males, white eyed males and white eyed females in F₂ generation. 

• A

   2 (red eyed females) : 1 (red eyed male) : 1 (white eyed male)

• B

  1 (red eyed females) : 1 (red eyed males) : 1 (white eyed female) : 1 (white eyed male)

• C

  1 (red eyed females) : 2 (red eyed males) : 1 (white eyed female)

• D

  1 (red eyed females) :  (red eyed males) : 2 (white eyed female)
