Mrs. Canal is type A and Mr. Canal is type O. They have two children named Greg and Rosalind. Greg is type 0 and Rosalind is type A.
What is Mrs. Canal's genotype? How do you know?
IᴬIᴬ , because Rosalind is A
Iᴮi because Rosalind is A.
Iᴬi because Greg is type O
ii because it is a universal donor
Two parents think their baby was switched at the hospital. The mother has blood type O, the father has blood type AB and the baby has blood type B.

Mom genotype is ii, Dad genotype is IᴮIᴮ
Mom genotype is ii Dad genotype is IᴬIᴮ
Mom genotype is ii Dad genotype is ii

In the image above, the trait for flower color is controlled by codominance. R codes for red flowers and W codes for white flowers. Which of the following correctly reports the phenotypes?
100% red flowers
50% white flowers and 50% pink flowers
50% red flowers and 50% red and white flowers

The image above shows the incomplete dominant cross where D codes for straight hair in dogs and d codes for curly hair in dogs. The incomplete dominant trait is wavy hair. Which of the following statements is true about the offspring?
Only the heterozygous genotype can code for wavy hair.
Only the homozygous dominant genotype can code for wavy hair.
Only the homozygous recessive genotype can code for wavy hair.
The homozygous recessive and homozygous dominant genotypes can code for wavy hair.

Diamonds
Squares
In a pedigree chart, women are represented by
Circles
Diamonds
Squares
In a pedigree, individuals that are affected are represented as shapes that are
Not shaded
Fully shaded
Half shaded
In this pedigree, the shading represents people in the family with dark hair while the unshaded represents blondes. Is dark hair controlled by a dominant or recessive allele?
Dominant
Recessive
Individuals that are shaded in have premature hair whitening. Is this trait dominant or recessive? How do you know?
Dominant because it skips generations
Dominant because it is present in every generation
Recessive because it skips generations
Recessive because it is present in every generation.
