Transcript Genetics Chalkboard Challenge

Genetics Challenge
• As a group, quietly discuss each
question and agree upon one
correct answer. The group with the
most correct answers will win.
1 of 20) Traits blend together during
which type of dominance?
2 of 20) What determines an organisms
phenotype?
3 of 20) Which type of dominance is
blood type?
4 of 20) Below is a pedigree that follows autosomal
recessive rules. What are the combined chances
that Ann and Michael have 3 unhealthy children?
5 of 20) Which genotype(s) will result
in type B blood?
6 of 20) While on a nature walk, you encounter a
beautiful Orange flower. You also see beautiful Blue
flowers. Out of curiousity, you decide to mate the Blue
and Orange flowered plants and are stunned to create
Green flowered offspring.
1) Which type of inheritance is this?
2) Create a Punnett square to show your results.

7 of 20) Mendel’s peas grew tall or short.
Cross two heterozygous plants.
(you should know which trait is dominant)
A)
What is the
probability of
growing
homozygous
plants?
B)
What is the
genotype of
short plants?
8 of 20) From the previous problem, what
is the probability of growing 3 tall plants?
9 of 20) How are Tom and Carla related?
10 of 20) A man, whose mother was a
hemopiliac, marries a woman with no history of
hemophilia in her family. In order, they had a
boy and a girl. Construct a pedigree of this
family and label the genotypes of all mentioned.
Hint: Hemophilia is sex-linked.
11 of 20) Red and white cattle coat shows
codominance and create a roan cow when they
reproduce. Cross a roan cow and a red bull.
What is the probability
of having a
heterozygous cow/bull?
12 of 20) Assuming autosomal recessive, what is
Michael’s genotype?
13 of 20) Match the diseases with the type
of inheritance.
Diseases:
Inheritance Patterns:
PKU
Autosomal recessive
Hemophilia
Autosomal dominant
Huntington’s disease
Sex-Linked
Colorblindness
Cystic fibrosis
Familial hypercholestmia (FH)
14 of 20) List the genotypes of every
person in this autosomal recessive
pedigree. Use the letter H or h.
15 of 20) A. How many blood type
alleles exist? B. Name them.
16 of 20) Does the pedigree below show a
dominant or recessive disorder?
17 of 20) Assuming autosomal recessiveness,
what is Alan’s genotype?
18 of 20) How many different phenotypes
are possible when a heterozygous type A
and type AB couple reproduce?
19 of 20) From the previous problem, what
is the probability of having type O blood?

legendary Paul Bunyan’s pet?
