If we are performing a cross involving seed color in garden pea plants and if we cross true-breeding parents with green seeds and yellow seeds then the F1 offsprings will have yellow seeds.

Since yellow seeds are dominant over the green seeds therefore in the first filial generation, all plants will have yellow seeds according to the Mendel's Law of Dominance.
The Mendel's Law of Dominance states that if two parents from two different pure-breeding lines with contrasting traits of a character are crossed, then only one of the traits appear in the filial 1 generation and that trait is the dominant trait. For example, having yellow seeds is the dominant trait in this case.

Thus, if we are performing a cross involving seed color in garden pea plants and if we cross true-breeding parents with green seeds and yellow seeds then the F1 offsprings will have yellow seeds.
