Question

The Punnett square below models the results of a cross of two flowers.

Punnett square with alleles B and b across the top and alleles B and b going down. Offspring in top left, top right, and bottom left cells have purple flowers. Offspring in bottom right cell has white flowers.
Each parent plant in the cross has blank flowers. The offspring of the cross have blank flowers.

So, the Punnett square shows that blank flowers.
reproduction results in blank offspring

Answer 1

Each parent plant has purple flowers (genotype Bb).
The offspring of the cross have purple and white flowers (3 purple : 1 white).
So, the Punnett square shows that sexual reproduction results in genetically varied offspring.
