What data would you expect to see regarding the distribution of phenotypes from a cross of purple pea plants that are heterozygous for flower color and plant height? (Purple is dominant to white;dwarf is dominant to tall. )
A)63 purple dwarf;25 purple tall;19 white dwarf;7 white tall
B)132 purple dwarf;138 white tall
C)54 purple dwarf;6 white tall
D)100% purple dwarf
E)27 purple dwarf;28 purple tall;31 white dwarf;29 white tall

The cross of heterozygous purple dwarf pea plants (PpDd x PpDd) would follow a dihybrid cross pattern, resulting in a phenotypic ratio of 9:3:3:1 for the traits in question. This translates to 9 parts purple dwarf, 3 parts purple tall, 3 parts white dwarf, and 1 part white tall, which matches the distribution given in option A when considering a total of 114 offspring (63 purple dwarf, 25 purple tall, 19 white dwarf, 7 white tall).
