Name______________________
1. Imagine that you were the person we now know to be the Father of Heredity, and it is at the end
of your life. On a separate sheet of paper write a first-person account of your life. Include at a
minimum five facts about you (name, location, etc.), five facts about the organism you studied,
and five of your discoveries. Also include a paragraph to reflect about your views about the
process of science, and relate your views to things that happened during your lifetime or that you
imagine might occur after your life is over.
2.
From the following word bank, select the 6 words for the particular chemical matter that
determines heredity, starting with the most specific and ending with the broadest.

3. Compare and contrast genotype with phenotype:
4. What are the following
homologous chromosomes,
homozygous alleles
heterozygous alleles
5. Contrast dominant, recessive, and incomplete dominance, providing an example of a
genotype and phenotype for all three.
6. Darth Maul is homozygous for his raspy voice, but Suzie Maul is heterozygous for her smooth
voice. Using the letter V (upper case V or lower case v as appropriate), prepare a Punnett
square to show the possibilities for their offspring.
7.
Both Neytiri a female Na'vi, and avatar Jake Sully are heterozygous for their blue skin. Blue skin
is dominant in the Na’vi over flesh colored skin Using the letter S (upper case S or lower case s
as appropriate), prepare a Punnett square to show the possibilities for their offspring.
8. Where a pea plant with short height (h h) is crossed with a pea plant with tall height (HH),
a) show the Punnett square possibilities for their offspring, generation 2.
b) What is the probability of a short pea plant for a generation 2 plant? _____
c) What is the probability of a tall pea plant for a generation 2 plant? ______
d) Show the Punnett square possibilities where one generation 2 is crossed with a second
generation 2 plant:
e. What is the probability of a short pea plant for a generation 3 plant? ________
f. What is the probability of a tall pea plant for a generation3 plant? _______
9.
