Question

What are the steps to do a punnett square?(number and list the steps)

Answer 1

First you determine the genotypes of the parent organisms. Second, Write down your "cross" (mating).  Write the genotypes of the parents in the form of letters (ex: Tt x tt). Third, draw a p-square. Fourth,you "split" the letters of the geno type for each parent & put them "outside" the p-square. fifth,you need to  determine the possible genotypes of the offspring by filling in the p-square. sixth, Summarize the results (genotypes & phenotypes of offspring).
