A punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes. Determine the possible offspring phenotypes. The father has a probability of 50% of passing on either of his two alleles.

Dihybrid punnett square solutions 1. A punnett square can be used to determine a missing genotype based on the other genotypes involved in a cross. Given four possible gamete types in each parent, there are 4 x 4 = 16 possible f2 combinations, and the probability of any particular dihybrid type is 1/4 x 1/4 = 1/16. Creating a punnett square and using it to determine traits of offspring is called performing a cross… Biol 366 mono and dihybrid crosses recitation problem set directions: These phenotypes and numbers are entered in columns 1 and 2 of the following table 2.
