Solution

The correct option is D 50 : 50
The yellow seeds are dominant to green seeds. The heterozygous yellow seeded plant will have the genotype Yy and the green seeded plant will have yy. If these two plants are crossed, the result of F $_{1}$ generation will be two Yy (yellow seeds) and two yy (green seeds). The probability of the offsprings will be 50:50.
Thus, the correct answer is option D.
