Answer:
F1= All Yy
F1= All yellow
F2= 1/4 YY: 1/2 Yy: 1/4 yy
F2= 3/4 yellow: 1/4 green
Explanation:
The allele for the yellow-colored seeds (Y) is dominant over the allele that imparts green phenotype (y). A cross between two pure breeding yellow seeded and green seeded plants would obtain all yellow seeded plants in the F1 generation. Self-pollination of F1 progeny would obtain F2 generation in following phenotype and genotype ratio:
Phenotype ratio= 3/4 yellow: 1/4 green
Genotype ratio= 1/4 YY: 1/2 Yy: 1/4 yy
