When a dominant yellow seed-bearing plant (YY) is crossed with a recessive green seed-bearing plant (yy), the F1 generation will all be heterozygous yellow seed-bearing plants (Yy). When the F1 generation plants are crossed, the possible genotypic ratios are YY:Yy:yy in a 1:2:1 ratio, and the phenotypic ratio is 3 yellow:1 green. Therefore, the approximate phenotypic ratio among the F2 generation would be 3 yellow:1 green.
