Respuesta :
The expected ratio of phenotypes in the following generation when a plant with white flowers and a heterozygous red flowering plant are crossed is 4red, 0 white (option-b).
What results from the union of a red flower and a white flower?
A red flowering plant and a white flowering plant are crossed, and all of the offspring have pink flowers. This cross serves as an example of how red and white only exert partial dominance. The mixing of the two alleles is what causes this situation.
Red and white flowered plants will be produced in equal amounts when heterozygous red (dominant) flower (Rr) is crossed with the white flower rr. Therefore, choice A is the appropriate response.
