Question

In Snapdragon, a cross between true-breeding red flowered (RR) plants and truebreeding white flowered (rr) plants showed a progeny of plants with all pink flowers.

The appearance of pink flowers is not known as blending. Why?

Solution

When the red and white flower varieties of snapdragon are crossed, the F1 progeny exhibits pink colour flowers. It is not known as blending inheritance because in blending inheritance, the characters are mixed in the offspring and do not segregate.

  Is there an error in this question or solution?
