When Mendel crossed pea plants with green pods with those with yellow pods, the offspring all had green pods if the green pod parent was homozygous. If the green pod parent was heterozygous, then half the offspring had green pods and half had yellow pods.
If green pea pods are dominant over yellow pea pods, all offspring from the cross will have green pea pods. This is because the dominant trait (green) will mask the recessive trait (yellow) in the heterozygous offspring. The genotype of the offspring will be heterozygous for the pod color trait.
Both yellow pea plants and green pea plants can produce pea pods containing seeds that can be cooked and eaten as a nutritious vegetable. The color of the seeds inside the pods will match the color of the parent plant's seeds, so yellow pea plants will produce yellow seeds while green pea plants will produce green seeds.
The F1 generation will all have yellow pods because yellow is dominant over green. This is because each parent plant is true-breeding and would only contribute the dominant yellow allele to their offspring.
A plant with yellow pods can never be a hybrid because yellow pod color is controlled by a recessive allele, meaning the plant must inherit two copies of this allele to display the yellow color trait. Therefore, a plant with yellow pods necessarily has two copies of the recessive allele and cannot have a dominant allele for green pods.

only green-podded plants. Incorrect^ Letter D on the sheet, about three-quarters green-podded plants and one-quarter yellow-podded plants.

The yellow pods make up 25%, the Green pods make up the other 75%.

This is one of the classic experiments carried out by Gregor Mendel. If you cross pure-breeding green pod plants with pure-breeding yellow pod plants the offspring (F1 generation) will all have green pods. This means that green pod is dominant and yellow pod is recessive. To explain the results, pure-breeding green pod plants must have the genotype GG (homozygous dominant) and yellow pod plants must be gg (homozygous recessive). When they are crossed the F1 offspring will receive a G allele from the green parent and a g allele from the yellow parent, so they will all have the genotype Gg ie they will be heterozygous.
Yellow pods are a recessive trait and for this type of trait to show in the phenotype, both alleles have to be recessive. If there was a recessive allele (yellow) and a dominant allele(green) as it shows in hybrid pods, then the dominant allele would be the one shown and the pod would be green.
