When you cross a true breeding tall purple flowered pea plant with a true breeding short white flowered pea plant (the parental or P generation), the offspring (F1 generation) are all tall purple flowered pea plants.

If we crossed one F1 plant with another F1 plant what are the possible phenotypes that we would observe?
How do the new phenotypic combinations observed in the F1 cross relate to chromosome behavior during meiosis?

These plants have phenotypes that are a blend of the phenotypes of their parents. For instance, the offspring (F1 generation) of a true breeding tall purple flowered pea plant that is crossed with a true breeding short white flowered pea plant will all be tall purple flowered pea plants.
