Usually when you are trying to figure out different possibilities of offspring using punnet squares, 4 genotypes can be figured out. I think that it also depends on how you are finding out the different genotypes for offspring.
Natural selection is a theory developed by Charles Darwin. It is believed that animal species evolve by nature "selecting" the ones that are fit to live in specific environments. For example, if an animal lacks a trait that is needed for a certain environment, it is likely to die. The animals that have the needed traits are more likely to live and procreate, which will pass on the trait to its offspring. Hope this helped!
