WebThe most simple crosses deal with only two alleles for the same gene, thus resulting in usually a dominant and rececssive relationship, or a codominat relationship etc. However … Web30 de jun. de 2016 · I just had a question here really to do with genetic crosses. I've been looking at Mendel and the experiments he carried out. One specifically looking at short pea plants. I'm looking at an example where all F1 plants are tall (F1 being the generation of plants). In the example the F2 generation are created in selfing the F1 plants.
