Why do we call problems about codominance and incomplete dominance "Non-Mendelian genetics?"
Because Mendel never learned about these things!

True or False:
Multiple alleles refers to traits that are coded by exactly 2 forms of a gene.
True or False:
Multiple alleles means that a person has many alleles for one gene, such as BbB.
False!
False!
200
How many alleles does each person get for each trait?
2! One from each parent.

How is our notation different when completing problems of codominance and incomplete dominance? In other words, how do we write individuals' genotypes DIFFERENTLY?
We use TWO different letters, BOTH of which are uppercase.

What is an allele?
Alternative form of a gene for each trait of an organism.

Flower color in some plants is controlled by codominance. What are the genotypic and phenotypic ratios when I cross a plant with black flowers and a plant with black and white-spotted flowers?
Complete a Punnett square.

A man with hemophilia has the genotype X^h Y.
He wants to marry a woman with the genotype X^H X^h.
Is there a possibility that their children will have hemophilia? Demonstrate using a Punnett square.

A man with type A blood marries a woman with Type O blood and they have four children, all type A.
a. What is the most probable genotype of the man?
b. What is the genotype of the woman?
a. AA
b. OO

What kind of square do we use to perform genetic crosses? Why do we use it?
Punnett Square, because we can predict the gene pairs from parent to offspring

The black and white spots characteristic of cow fur are an example of incomplete dominance.
TRUE OR FALSE?
FALSE! Codominance!

Point out an example of a trait on your body. Do you think this trait is dominant or recessive? Codominant or incompletely dominant? Multiple allele or sex-linked?
How do you know/ why do you think so?

In humans, normal vision (XC) is dominant to colorblindness (Xc) and is sex-linked. A normal-visioned man, whose father was colorblind, marries a colorblind woman. What are the chances that a son will be colorblind? A daughter? Explain using a Punnett square.

4. Normal male.

Two type AB parents took home a newly born type A baby from the hospital and decided it was not their baby because it did not seem to resemble either of them. They claimed another couple had their baby.
Is this claim justified? Could this baby possibly be theirs? Use a Punnett square to find out!
