According to my understanding of mendel, the F1 generation is about 50% parental mix, 25% mom dominant and 25% father dominant traits. This works well with distinctly different inbred lines. The subsequent F2 generation will express traits going all the way back to great grandparent generations. With Mendels peas, his parents had purple and white flowers, the F1 generation had all purple flowers. Individuals with white flowers do not appear until the F2 generation where the recessive genes can pair up then we get all the 9:3:3:1 baloney....ooof. If we are hunting specific phenotypes they may not be expressed in an F1?
One of the issues is that mendel was working with monohybrid and not dihybrid crosses so we are not even taking into account incomplete and codominant traits.
Oh man my brain hurts ❤
