The basic rules of probability and Mendel’s Principle ofSegregation can also be used to predict the outcomes of morecomplex crosses. Consider the following dihybrid cross: Bb Tt X BbTt (A) What are the phenotypes of the two parents in this cross?(B) What is the probability that an offspring will be recessive forboth traits? HINT: Think of this in terms of probability. You don’tneed a Punnett Square. Determine the probability of a recessivephenotype for a single gene cross (ie. Bb X Bb OR Tt X Tt) and thenmultiply it by the probability for a recessive phenotype for thesecond gene. (C) What is the probability that an offspring will beheterozygous for both genes?
