Tallness in a particular plant is caused by a dominant


Tallness in a particular plant is caused by a dominant allele, the flower color is determined by genes which exhibit incomplete dominance (resulting in the colors purple, lavender and white). A tall, purple-flowered plant (which is heterozygous for height) is crossed with a tall, lavender-flowered plant (also heterozygous for height). What is the genotypic ratio of the offspring?

Select one:

a. 3 TTPP : 1 TtPP : 3 TTPP' : 1 ttPP

b. 1 TTPP : 2 TtPP : 1 TTPP' : 1 ttPP : 2 TtPP' : 1 ttPP'

c. 9 TTPP : 3 TtPP : 3 ttPP : 1 ttPP'

d. 1 TTPP : 1 TtPP : 1 TTPP' : 1 ttPP
