In a certain species of plant, flowers occur in three colors: blue, pink, and white. The genotype that produces white is ww. The presence of one W allele allows pink or blue color to occur. The B (blue) is dominant to b (pink). A pure-breeding pink plant is mated with a pure-breeding white plant. All of the F1 are blue. When the blue F1 plants are self-fertilized, the F2 plants occur in the ratio 9 blue : 3 pink : 4 white. What is the genotype of the original white parent

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

not sure if this is what you'r looking for eubacteria and archaebacteria
