Green and red colored seeds are recessive and dominant trait respectively. Out of F1 and F2 in which generation will the green seed appear, if both parents are not hybrid.

In Mendelian genetics, the appearance of traits like seed color depends on the alleles inherited from the parents.

Green seeds are recessive (represented by “gg”).
Red seeds are dominant (represented by “GG” or “Gg”).
If both parents are not hybrid (homozygous), it means that both of them have the same genotype for seed color. Let’s assume both parents have red seeds, which means they are “GG.”

F1 Generation:
When you cross two parents with the genotype “GG,” all their offspring (F1 generation) will have the genotype “Gg” because they inherit one allele from each parent. In this case, they will all have red seeds because the dominant allele “G” determines red seed color.

F2 Generation:
Now, if you take two F1 generation individuals with the genotype “Gg” (both having red seeds) and cross them, you will get an F2 generation. In the F2 generation, there is a possibility for green seeds to appear because the genotype “Gg” is heterozygous. When two heterozygous individuals are crossed, there is a 25% chance of getting offspring with the recessive genotype “gg,” which results in green seeds.

So, green seeds are likely to appear in the F2 generation when both parents are not hybrid and have red seeds (GG).
