Please excuse my kids and dogs toward the end, lol!

Question 1
1.

How are traits passed from parent to offspring?

There is no right or wrong answer, this is simply what you think!

You can use the blue plus sign in the upper right of the response box to choose "Audio" or "Video" to record yourself instead of typing.

Consider the following Punnett Square:


What would be the result of a cross between a homozygous dominant purple flower and a heterozygous purple flower?

Complete the Punnett Square in "Show Your Work," then summarize your results.

Genotype Results
__________ BB
__________ Bb
__________ bb

Phenotype Results
__________ purple flowers
__________ white flowers
Question 5
5.
In guinea pigs, fur color can be black (B) or white (b). Fur length can be short (L) or long (l).

What possible gamete combinations could this guinea pig produce? Use the FOIL method.


_______ _______ _______ _______
Question 6
6.

Which guinea pig would have the genotype bbll?

Question 7
7.

How can we represent traits over several generations?

There is no right or wrong answer, this is simply what you think!

You can use the blue plus sign in the upper right of the response box to choose "Audio" or "Video" to record yourself instead of typing.

Question 8
8.

In humans, albinism is a recessive trait. The disorder causes a lack of pigment in the skin and hair, making an albino appear very pale with white hair and pale blue eyes. This disorder can also occur in animals, a common albino found in a laboratory is the white rat.

Draw a pedigree where two carrier parents (Aa) have 3 children: a normal female, an albino son, and a normal female.

The youngest daughter marries a man and they have an albino daughter.

Don't forget to label the generations and individuals. Add the genotypes of each individual.

Hint: there are carriers in generation II!

Question 9
9.

Are there traits that don't follow the dominant/recessive rules?

There is no right or wrong answer, this is simply what you think!

You can use the blue plus sign in the upper right of the response box to choose "Audio" or "Video" to record yourself instead of typing.

10.

Question 11
11.
What are the possible genotypes and phenotypes of the offspring of two carrier parents for sickle cell anemia (NS)?

Let N represent the normal gene.
Let S represent the sickle cell gene.

Justify your answer with a Punnett Square in "Show Your Work."

Genotype results
__________ NN
__________ NS
__________ SS

Phenotype results
__________ Normal red blood cells only
__________ Normal & sickle red blood cells
__________ Sickle red blood cells only
Question 12
12.

How are you feeling about this unit? Do you have any questions? Do you need any extra help?

Heterozygous
Genetic code of the individual
Recessive
The expression of a gene that can be observed
Genotype
Trait that is always expressed in the phenotype
Homozygous
Trait that is only expressed if no dominant allele is present
Dominant
Two identical alleles
Phenotype
Two different alleles
Categorize these alleles into homozygous or heterozygous
Tt
AA
rr
Ss
TT
yy
Homozygous
Heterozygous
A couple had a baby with type O blood. "That's impossible!" the mother said, "I have type A blood and the baby's father has type B blood!"

Is the mother wrong? Justify your answer with a Punnett Square in "Show Your Work."
Yes, her baby could have type O blood
No, that's not her baby
