Bell Work
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?

1. What causes an adaptation to occur?
2. How does natural selection work to determine if a
mutation will become prevalent in a population?
Video Questions:
1. How did mutations play a role in the fur color of the
pocket mouse?
2. How did natural selection work to change the percentages
of light and dark colored mice on the lava flows?
3. After scientists decoded the genes of the mice, what was
something surprising that they noticed across a wide
variety of dark colored mice?

the green fish to die?

organisms involved:
“A worm grows inside a snail, and then causes the snail to
climb out into the open so it can be seen easily by birds. A
bird eats the snail and the worm. The worm doesn’t die,
but it can only reproduce in the gut of the bird. The bird is
unharmed by the worm.”
