Download Label each of the following as homozygous or heterozygous

CODOMINANCE
 In dogs, gum coloration is co-dominant, with black
coloration, black & pink spotted and pink.
 You have a lovely spotted gummed Labrador retriever
who has just had 8 pups. Four of the pups have
spotted like your dog, and 4 have black gums.
31. What is the likely phenotype of the sneaky neighbor
dog? Show your work.
INCOMPLETE DOMINANCE
 In Andalusian chickens, feather color is inherited
by incomplete dominance. If one parent with
black feathers (BB) is crossed with a whitefeathered parent (bb), all of the offspring will have
blue feathers (Bb).
32. What is the percent chance of producing bluefeathered offspring when crossing a blue-feathered
hen with a white feathered rooster?
BLOOD TYPE
 Sometimes Blood Type alleles are written like those
below:
23. Write out what the Genotype & Phenotype are for the
F1 Generation
DUCHENNE’S MUSCULAR DYSTROPHY
 This type of Muscular Dystrophy a sex linked
genetic disorder that results in muscle degeneration
and eventual death  caused by a mutation in the
dystrophin gene, the largest gene located on the
human X chromosome which codes for the protein
dystrophin, an important structural component
within muscle tissue that provides structural
stability to the dystroglycan complex (DGC) of the
cell membrane.
29. Cross a carrier with a male who is normal for the
dystrophin gene and give the Genotype & Phenotype
for the F2 Generation.
LAW OF SEGREGATION
12. State the Law of segregation.
HOMOzygous vs hEtErOzygous
2. The term HOMOzygous describes ---.
3. The term hEtErOzygous describes ---.
4. Label each of the following as homozygous or
heterozygous:
Purple

white
MONOHYBRID CROSS
Hawaiian happy face spiders from the island of Maui can
have different markings, as shown below. A single gene
determines the markings on the spiders.
A plain spider is crossed with a patterned spider. The
patterns spider is homozygous. The pattern allele is
dominant to the plain allele.
5. What percentage of the offspring from this cross
are expected to be patterned rather than plain?
A. 0%
B. 25%
C. 50%
D. 100%
POLYGENIC INHERITANCE
16. What is polygenic inheritance?
17. Give two examples.
DIBYBRID CROSS
22. If the F2 generation resulted in a 9 : 3: 3 : 1
phenotypic ratio, what would the genotype of each
parent be? Use letters of your choice.
SEX LINKED INHERITANCE
13. Why are males more likely to inherit a sex linked
trait like Color Blindness or Hemophilia?
14. Write the genotype for a color blind male.
CODOMINANCE
 Leaves from two white clover plants, each with a
different pattern, are shown below. These flowers
exhibit codominance.
15. If these two flowers were crossed, draw what the
offspring would look like.
KARYOTYPE
10. Is the karyotype below from a human?
11. What sex is represented on the karyotype?
LAW OF INDEPENDENT ASSORTMENT
28. According to Mendel’s Law of Independent
Assortment, what would be the expected allele
combinations produced by the chromosomes
below?
GENETIC ENGINEERING
 The picture shows a process by which scientist take
DNA from a human pancreas and inject it into the DNA
of bacteria, thus making a new organism called
Recombinant Bacteria.
30. What are these types of organisms called?
DIHYBRID CROSS
 Fill in #8 and #9 with the correct genotypes.
8.
9.

25. From the above pedigree, what type of genetic
disorder can you infer that it represents?

27. Describe, using a Punnett square, how the F1
generation was determined (determine the genotypes
of the parents and do a Punnett square)
PEDIGREE CHART

19. What do you think the line through the symbol
means?
20. What person in Generation II would be homozygous
dominant?
21. What person in Generation III would be homozygous
dominant?
