In a certain species, the allele for blue flowers (B) is dominant over the allele for white flowers (b). If two blue-flowered plants, both heterozygous (Bb), are crossed, what is the expected phenotypic ratio of the offspring?
1:1
3:1
1:2:1
2:1
The cross Bb x Bb results in a phenotypic ratio of 3 blue (BB or Bb) to 1 white (bb), which is 3:1.
