In radishes, a bent root is a dominant trait, though some roots are straight (which is recessive).
Paul andersen introduces the punnett square as a a powerful tool in genetic analysis. In radishes, a bent root is a dominant trait, though some roots are straight (which is recessive). It is used to predict the possible offspring from a cross, or mating between two parents. It is important that you understand the steps in the extraction procedure and why each step was necessary. Therefore, we have to calculate what would happen in each case.
Creating a punnett square requires knowledge of the genetic composition of the parents. Includes worked examples of dihybrid crosses.
