I'm preparing myself for the GRE. The quantitative stuff has all been going well. I'm aiming for a geology grad scheme. In the event of having to take subject specific tests, I'm teaching myself a few "out there" things in science.
I'm going through biology and looking at genetics for the first time since high school(!)
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.
Now, I've got my head around the science involved, but I just basically wondered if any biologists here could show me how to make a genetic cross of F2 in order that I could show the genotypes and phenotypes of the offspring.
This isn't necessary but I feel as though it would help my understanding.
At the moment I'm drawing a two by two grid. I suppose I need to fill it with the appropriate alleles?
