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) Examine this pedigree for a sexlinked recessive disorder. Using the letter
“H”, fill in every person mentioned.
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 more 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.
Which type of inheritance is this?

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) Peter marries Lois. Peter’s mother was
a hemophiliac, but Lois has no history of
hemophilia in her family. Together, they had
Chris, Meg, and Stewie. Construct a pedigree
showing the 5 people named and label their
genotypes. Hint: Hemophilia is recessive sexlinked.
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 offspring?
12 of 20) Assuming autosomal recessive, what is
Sam’s genotype?
13 of 20) Match the diseases with the type
of inheritance.
Inheritance Patterns:
Autosomal recessive
Diseases:
A) PKU
B) Hemophilia
Autosomal dominant
C) Huntington’s disease
D) Colorblindness
E) Cystic fibrosis
Sex-Linked
F) 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) Two part question:
A. How many blood type alleles exist?
B. Name them.
16 of 20) Pretend that dominant purple flowers and
recessive fuchsia flowers blend to make yellow flowers.
Cross a yellow flower parent with a purple flowered
parent. What’s the odds of producing a yellow flowered
offspring?
?
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?
