  1. Dominant Traits Punnett Square Practice • GROUP PRACTICE • Choose 1 Simple Dominant Trait and complete the steps 1-4 for each trait • For each square report the fractions and percentages for the possible genotypes and phenotypes • 1. One parent is homozygous dominant and one parent is homozygous recessive. • 2. Both parents are heterozygous • 3. One parent is homozygous (recessive or dominant) and one parent is heterozygous • 4. Cross two potential offspring from the examples above

  2. Short hair is dominant to long hair in guinea pigs. • Two short haired guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. What are the probable genotypes of the parents?  • Show a cross to provide evidence to your statement.

  3. Flower Pre-Lab • Make a key to show what each color of chemical represents for flower color. 2. Write the number of solutions that go in each test tube. 3. Summarize in 3 sentences or less the purpose of this experiment. 4. List at least 3 safety concerns or procedures.
