Assume that plant height and flower size in Four O'Clock plants display antogonistic phenotypes. Four O'Clock plants can be tall or short and the flowers can be large or small. Assume each trait is governed by alleles of a single gene and that each follows Mendelâ's first and second laws. You start with two pure breeding strains, one that is tall with large flowers and a second that is short with small flowers. You cross these two strains to each other to generate F1 plants. You self-cross an F1 plant and grow 342 of the resulting seeds into plants. You find that 195 plants are short with large flowers, 62 plants are short with small flowers, 59 plants are tall with large flowers, and 26 plants are tall with small flowers.

For the cross above- what is the phenotype of the F1 individuals?

A. Short with small flowers
B. Tall with small flowers
C. Medium height with medium size flowers
D. Short with large flowers
E.Tall with large flowers
F. Can't tell from the information provided
