The complete question is described in the image given below:

When a Parakeet that is heterozygous (Bb) for blue feather (dominant) is crossed with a Parakeet that is purebred (bb) for white feather (recessive), the genotypes of the resultant offspring are Bb, bb, Bb, and bb.

In which 50% of the offspring possess blue feathers (Bb) while 50% of the offspring possess white feathers (bb).
