.In the rosees,the red flower colour (R) is incompletely dominant over white flower (r).The heterozygotes produce pink flowers.A red flower rose plant was crossed with a plant with white flowers,and their F1 intercrossed to produce F2.
a)What were the genotype of the F1 and expected proportions? (8 marks)
b)If the F1 are backcrossed to the white plant,what will be the genotype and phenotypes of the offspring? (6 marks)
c)If the F1 are backcrossed to the red plant,what will be the genotypes and phenotypes of the offsprings? (6 marks
