10/1/12
When Mendel crossed a “pure-breeding” purple pea plant with a “pure-breeding” white pea plant, all of the offspring in the F1 generation were purple.
  1. What were the genotypes of the two parent flowers?
  2. Draw a Punnett square to show the cross. What do you notice about the genotypes of the offspring?
10/2/12
  1. In blood type, the A allele and B allele are both dominant. What kind of dominance is this called?
  2. If a person has the genotype AB for blood type, then their phenotype (blood type) is written as “Type AB,” but if a person has the genotype AO for blood type, their phenotype (blood type) is just written as “Type A.” Why?
10/3/12
  1. Write an example of a homozygous dominant genotype.
  2. Write an example of a homozygous recessive genotype.
  3. Write an example of a heterozygous genotype.
  4. For complete dominance, what trait will we see for an organism with a heterozygous genotype?
