The correct answer is: $50: 50$
Yellow seeds are dominant is green (Y). So, a heterozygous yellow seeded plant will have the genotype of $(\mathrm{Y}, \mathrm{y})$ and a green seeded plant will have genotype (yy). When these plants are crossed, the $\mathrm{F}_1$-generation will have the ratio of yellow : green as 50 : 50 .
