  1. Warmup10/28/14 What do you think happens if you cross a red rose with a white one? Explain Objective Tonight’s Homework To learn how to calculate dihybrid Crosses pp 136: 1, 2

  2. Practicing Dihybrid Crosses List the genotype and phenotype chances for the dihybrid crosses below. Peas: If “R” is round, “r” is wrinkled, “G” is green and “g” is yellow… - Cross a “Rrgg” pea and a “rrGG” pea - Cross a “RRGg” pea and a “rrgg” pea - Cross a “rrGg” pea and a “RrGg” pea

  3. Exit Question #25 Which definition below would fit "dihybrid cross“ a) The probability for only heterozygous gene crosses. b) The probability for only homozygous gene crosses. c) The probability results for just one trait. d) The probability results for looking at two traits at once. e) The probability results for traits that mix. f) None of the above
