Define the following terms:

Heterozygous/hybrid
Homozygous/purebred
Co-dominance
Incomplete Dominance
Testcross
DEFINITION
9.
Red is dominant to yellow in certain flowers. Cross two plants that are both hybrid for red flower
color:
10. Two pea plants are both heterozygous for the dominant traits of tall height and purple flowers. (short
height and white flowers are recessive) What is the probability that a cross of these two plants will
produce a white flowered, short plant?
11. In monsters, having two heads is dominant over having on head. Is a two head heterozygote monster
was to mate with a one headed monster, what would be the genotypic and phenotypic ratios of their
children?
12. If the above is true about monsters, and you had a monster with two heads and did not know its
genotype, how could you figure it out? What would you need to do? What is this process called? Show
how you would solve this problem
13. In pigs, straight tails are incompletely dominant with curly tails. When they form a hybrid, they make a
wavy tail. Cross a straight tail pig with a wavy tail pig. Show your Punnett square and list the genotypic
and phenotypic ratios. Why is this incomplete? Explain.
14. In turtles, yellow shells and pink shells are co-dominant. The hybrid will have a yellow shell with pink
spots. Cross a spotted shell with a yellow shell. Show the genotypic and phenotypic ratios and prove
your work with a Punnett square. Why is the mode of inheritance co-dominance? Explain.
15. A woman with type O blood gives birth to a child with type B blood. The man that she is accusing of being
the father has type AB blood. Can he be the father of her child? Explain why or why not and prove with a
Punnett square.
16. In cats, having green eyes is co-dominant to having yellow eyes. The hybrid will have one
green eye and one yellow eye. Cross two hybrid cats. What is the chance that they will have
four female cats in a row with green eyes? What is the chance that they will have five male
cats that each has one green eye and one yellow eye? Show your work in a Punnett square.
4 female cats with green eyes?
5 male cats with one green and one yellow?
What about this trait makes it co-dominant dominant?
17. Hemophilia is a sex linked recessive trait. Cross a normal man with a female that is a carrier. What is the
probability that they will have any children with hemophilia? Show your Punnett square and the
genotypic and phenotypic ratios.
18. Brianna and Bryan marry. They had 5 children, Christina, Cassie, Jenna, Rob, and Nick. Christina, Jenna,
and Nick all have pink hair; Cassie, Rob, Brianna, and Bryan are normal. Christina went on to marry a
normal man named Kyle. Kyle’s father, Ken, had pink hair but Kyle’s mother Jessica does not. What is the
likelihood that Kyle and Christina will have pink haired children? (Draw the pedigree.)
19.
What type of trait is this? Autosomal or Sex linked? Dominant or recessive? Why?

If individual III-6 married a man that was a carrier for the disorder, what would the chance of them having a child
with the disorder be?
20.
