Beginner's guide to punnett squares. paul andersen introduces the punnett square as a a powerful tool in genetic analysis. he tries to address major misconceptions that students have when use a punnett square. he gives a number of examples of monohybrid crosses and one example of a dihybrid cross. In garden peas, yellow seeds (y) are dominant to green seeds (y), and inflated pods (i) are dominant to constricted pods (i). suppose you have crossed yyii parents with yyii parents. draw the f2 punnett square. based on this punnett square, predict the expected phenotype (s) in the f2 generation and the expected frequency of each phenotype. The f 1 cross would be drawn as in figure 1.5.1. as you can see, in a monohybrid cross, the offspring ratios will be 3:1 of dominant phenotype (purple): recessive phenotype (white). punnett squares can also be used to calculate the frequency of offspring. the frequency of each offspring is the frequency of the male gametes multiplied by the.

Summary. a punnett square is a chart that allows you to determine the expected percentages of different genotypes in the offspring of two parents. a punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes. a punnett square can be used to determine a missing genotype based on the. Paul andersen introduces the punnett square as a a powerful tool in genetic analysis. he tries to address major misconceptions that students have when use a punnett square. he gives a number of examples of monohybrid crosses and one example of a dihybrid cross. the square is a simple tool that uses the outcome of meiosis to determine possible offspring in a cross.
