tall, violet x tall, white

The representation will be

DDWW × DDww (We the apply the mendelian crossing)

This will yield offsprings with the following trait

DDDD × DwDw

DWDW x WwWw

DdWw x ddww

Ddww x ddWw

DdWw x DdWw

DDWw x ddww

From the above Offsprings

1/2 tall, white and 1/2 tall, violets offspring are
