Welcome
to the
Genetic Cross
Challenge
Question 1
Give an example of:



Incomplete dominance
Complete dominance
Codominance
Question 2
If black fur is dominant to tan fur for guinea
pigs, what are all of the possible
genotypes for black fur guinea pigs?
Question 3
In order for a recessive trait to be
expressed the genotype must be what?
Question 4
If you walk up the stairs four times and
down the stairs four times in one school
day, what is the probability that you will fall
while walking on the stairs in one school
day?
Question 5
What are all of the possible phenotypes of
the offspring of a homozygous purple
flower and a homozygous white flower?
Purple coloration is dominant.
Question 6
If a red flower and a white flower were
crossed. What would the phenotypes be if
this specific species flower coloration was
an incompletely dominant trait?
Question 7
You have just received a new pet! You now
have a brown rabbit in the family. You
know, from your great biology class, that
brown fur color in dominant in rabbits. You
want to decipher the genotype of your new
pet. What should you do? Show all
possibilities.
Question 8
What do you think the last name of the
man was who helped develop a way to
predict the outcome of a genetic cross?
Question 9
If eye color were codominant in human
beings, what would the offspring of a
brown eyed man and a blue eyed woman
look like?
Question 10
Complete the following:

BbRr x bbRr
Question 11
How many offspring would be tall with
purple flowers if two pea plants were
crossed which were heterozygous for both
traits?
Question 12
How many albino, smooth-haired guinea
pigs would be produced from the cross of
a homozygous dominant male for both
traits and a homozygous recessive female
for both traits?
