The possible offspring of green and yellow pods receive half of their DNA from each parent. This is through the process of genetic recombination during sexual reproduction, where genetic material from both parents combines to create a unique combination in the offspring.
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.
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.
The genotype of the offspring with yellow pods is likely homozygous dominant (YY) or heterozygous (Yy), assuming yellow pods are dominant over green. The possible genotypes of the offspring with green pods would be homozygous recessive (yy), as green is the recessive trait. If both yellow-podded parents are heterozygous (Yy), some offspring could also be yellow (YY or Yy) while others could be green (yy).

The yellow pods make up 25%, the Green pods make up the other 75%.
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.
Green is the dominant trait in this cross. Mendel's results demonstrate that when a dominant allele (for green pods) is present, it masks the effect of the recessive allele (for yellow pods), resulting in all offspring exhibiting the dominant phenotype. Thus, the true yellow podded plant contributes a recessive allele that does not express in the presence of the dominant green allele.
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.

only green-podded plants. Incorrect^ Letter D on the sheet, about three-quarters green-podded plants and one-quarter yellow-podded plants.
In accordance to Medelian's first law,you will receive a F1 (Generation 1) of all the dominant traits (If you G is Green,it will be all green and if you G is yellow,it will be all yellow).It is only when during F2 (Generation 2) as you interbreed them (F1 x F1) will you receive a Phenotypic ratio of 3:1.In this,if your G is green,it will be of a ratio of 3 greens to 1 yellow pea pods. Basically Gg x Gg will give rise to 2 phenotypic classes of progeny,G and g,in a ratio of 3:1 provided that G is Dominant to g.
