Question

Name: (Last) (First) Section: 8. Flower color (20 Points) Plant X can produce magenta, blue or breeding white flower plant to a true b from this cross produced blue flowers. He se blue flowers, 398 white flower- and 301 magenta flower-prou generation agenta, blue or white flowers. A gardener crossed a true int to a true breeding magenta plant. All Fl progenies lue flowers. He self-crossed the Fls and obtained 895 magenta flower-producing plants in the F2 a. What is the most likely genetic explanation for this result? (Hint: pathway) b. What is the genotype of the parental white flower producing plant? c. Based on your hypothesis, what are the genotypes of each phenotypic group in F2 and the ratio of these groups? What form of inheritance is this (Complementation, recessive epistasis, dominant epistasis, duplicate genes, etc.)? d. Does the data support your hypothesis? (Hint: )

Answer 1

The given data is given data is as follows. The h in dosduals include 895 blue to 95 blue flowers, 398 white flowers and 301 Magenta flowens , Total population is 398 +301= 699 which is equal to 699 = 43.6 16 The expected phenotype would be 12:3:1 2 x 699 = 524 - x 699 = 131 16 I x 699 = 43.6 This 12: 3 1 figures are very Indicating close to the ratio Dommant repistass.
