Considering the Mendelian traits tall (D) versus dwarf (d) and violet (W) versus white (w), consider the crosses below and determine the genotypes of the parental plants by analyzing the phenotypes of the offspring.

Parental Plants Offspring
tall, violet x dwarf, white 1/4 tall, violet
1/4 tall, white
1/4 dwarf, violet
1/4 dwarf, white

Select all that apply.

a. DDWW x DdWw
b. DdWw x ddww
c. Ddww x ddWw
d. DdWw x DdWw
e. DDWw x ddww

DDWw x Ddww

DdWw x DDww

DDWw x DDww

Explanation:

D for tallness

d for dwarfness

W for violet

w for  white

For Parental Plants that has

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

× DwDw

× DwDw

DWDW x

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

DDWw x Ddww

DdWw x DDww

DDWw x DDww
