Please help urgently

In a monohybrid cross and simple dominance, what is the probability of the dominant phenotype being expressed in the offspring? ½ 1:2:1 34 14 1:3:1

4). In papayas, sour fruit (S) is dominant over sweet fruit (s), and green skin (G) is dominant over yellow skin (g). The genes for these characteristics independently assort. A homozygous plant with sour fruit and green skin is crossed with a homozygous plant with sweet fruit and yellow skin. Two individuals from the F1 generation are then crossed to produce an F2 generation.
