PureBred tall plants with round seeds are crossed with purebred short plants with wrinkled seeds. Some of the offspring are then crossed with an unknown plant. The offspring from this second cross are 1/2 tall round and 1/2 tall wrinkled. What are the genoype and pheotype of the unknown plant?

TTRR x ttrr => The F1 generation: TtRr
TtRr x ? => 1/2 tall round TTRr + Tt Rr & 1/2 tall wrinkled Ttrr + TTrr
? = TTrr Tall wrinkled unknown

the genotype of the unknown plant is 2 purebred, tall plant with round seed crossed, while the phenotype is 2 purebred, shorts plantwith wrinklesd.
And it can denoted by TT(tall plant) and Tt(short plant) whem you cross breed it you will get what i mean

TTWw... it's tall with wrinkled seeds. Wait... assuming the wrinkled seeds are dominant. Is round supposed to be dominant? The question didn't say.
