Question
In garden pass, the following completely dominant traits are observed: T = tall P = purple flowers G = green seed pods t = short p = white flowers g = yellow seed pods. Cross a plant that is true-breeding tall with purple flowers and green seed pods (TTPPGG) to a plant that is true-breeding short with white flowers and yellow seed pods (tt pp gg). Give the genotype and phenotype ratios for the second generation. Points awarded for the following: F1 set-up, F2 set-up and F2 Punnett Square = 9 pts. F2 phenotypic ratio (if correct) = 12 pts. F2 genotypic ratio (if correct) = 15 pts. The maximum number of points you can receive is 15.Explanation / Answer
punnette square
F 1 generation -genptype =
Tt -4
Tp-4
Tg-4
Pt-4
Pp-4
Pg-4
Gt-4
Gp-4
Gg-4
phenotype - is 3 are Tall plants, 3 are purple flowers and 3 are greed pods.
F2 generatin

phenotype
tall = 9
tall and purple flowers=18
tall and green pods =18
purple flowers = 9
green pods = 9
tall and purple = 18
purple flowers and green pods= 18
