Genotype refers to the set of genes in our DNA which is responsible for a particular trait, while the physical expression or characteristic of that trait is known as the phenotype.

For this case, to know the genotype and phenotype of the offsprings and the parents, we will use Punnett Square.

If both parents have Bluewings (BB), all their offsprings will also have bluewings (BB).

Likewise, if one of the parents have purple wings (bb) while the other has blue wings (BB) all their offsprings will have red wings (Bb).

If one of the parents have bluewings (BB) while the other has red wings (Bb), 50% of the offsprings will have blue wings (BB), while the other 50% will have red wings (Bb).

If one of the parents has red wings (Bb) while the other one has purple wings (bb), 50% of their offspring will have red wings (Bb), while the other will have purple wings (bb).

Lastly, if both parents both have purple wings (bb), all their offsprings will have purple wings.
