8. PROBLEM #1
In a species of birds, blue feathers (B) are
incompletely dominant to the gene for white
feathers (b). Individuals that are heterozygous
(Bb) have blue-tipped feathers.
A bird with blue-tipped feathers is crossed
with a white bird. What is the chance that the
offspring will have blue feathers?
9. PROBLEM #1
A. 0%
B. 25%
C. 50%
D. 100%
(include your solution in Punnet square)
10. PROBLEM #2
In humans, three alleles affect
blood type. The A and B alleles are
codominant and the O allele is
recessive.
An AB blood type has children
with an A blood type mother
(genotype AO).
11. PROBLEM #2
What are the chance that their children will
have AB type blood?
A. 25%
B. 50%
C. 75%
D. 100%
(include your solution in Punnett square)
12. PROBLEM #3
A black sheep is bred with a white
sheep. All of their offspring have a
phenotype of gray coats.
What is the most likely pattern of
inheritance for coat color in sheep?
13. PROBLEM #3
In camellia flowers, petal color is
controlled by codominance. Find the
phenotypes of the offspring if a
scientist crosses a red flower (RR) with
a red-and-white (RW) flower.
14. PROBLEM #3
A. 75% RR, 25% WW
B. 50% RR, 50% RW
C. 100% RW
D. 100% RR

15. PROBLEM #3
A. Codominance
B. Lethal Allele
C. Multiple Allele
D. Incomplete Dominance
