NOTE: There are two parts to this problem (a & b), with each part having their own questions.
a) One dark purple and one white flowered plants were crossed to each other. A total of 20 seeds were harvested and planted. The following phenotypes were observed in the F1 generation:
5 dark purple, 9 light purple and 6 white
1. Calculate the phenotypic ratio
2. What is the most likely pattern of inheritance in this exercise?
3. How would you represent the genotype of the dark purple, light purple and white flowered plants?
b) Two light purple flowered plants were crossed with each other. What is the probability that a group of six offspring from this cross will be pomposed of two white, 1 light purple, and three dark purple-flowered plants? Clearly show work for the equation, the math, and the probability.
