What is the term for a person who has one recessive allele but does not show the trait?
Carrier

Recessive Pattern
Dominant Pattern
If flower color in snapdragons is incompletely dominant, what is the result when a red-flowered snapdragon (RR) is crossed with a white-flowered snapdragon (WW)?
Pink flowers (RW)
Red flowers (RR)
White flowers (WW)
Red/White striped flowers (RW)
What does the term "recessive pattern" mean in inheritance?
Includes carriers and can skip a generation
No carriers; unaffected parents cannot produce affected children
Both alleles show up equally
Two alleles are blended
What is the main difference between incomplete dominance and codominance?
Incomplete dominance blends traits; codominance shows both traits side by side
Incomplete dominance shows both traits side by side; codominance blends traits
Incomplete dominance affects more males than females; codominance affects both sexes equally
Incomplete dominance affects more females than males; codominance affects both sexes equally
Which pattern usually shows up in every generation because two unaffected parents cannot produce affected children?
Dominant Pattern
Recessive Pattern
Codominance
X-linked Pattern
If hair color in cows is codominant, what is the result of crossing a red-haired cow (RR) with a white-haired cow (WW)?
A roan cow (RW) with both red and white hairs
A red cow (RR)
A white cow (WW)
A pink cow (RW)
Which inheritance pattern can "skip" a generation?
Recessive Pattern
Dominant Pattern
Codominance
Incomplete Dominance

What is the inheritance pattern where only one copy of the allele is needed to show the trait?
Dominant
Recessive

Diamond
Why are males more likely to be affected by X-linked traits?
They have only one X chromosome
They have two X chromosomes
They have no X chromosomes
They have more dominant alleles
Which of the following is true about carriers of recessive traits?
They are homozygous recessive.
They are homozygous dominant.
They are heterozygous.
Cross a black fowl with a white fowl. What is the phenotype ratio?
How are Incomplete Dominance and Codominance different than a simple dominance cross?
The different forms of a gene are called
traits
pollinators
alleles
hybrids
The physical appearance of an organisms is its
Genotype
Phenotype
characteristic
Heterozygous
A trait that is located on the X chromosome is called
Multiple alleles
Codominance

Punnett Square: Type AB father and type O mother. What are the percentages of each offspring?
Type A: 50%, Type B 0%, Type AB 50%, Type 0 0%
Type A: 50%, Type B 50%, Type AB 0%, Type 0 0%
Type A: 25%, Type B 25%, Type AB 25%, Type 0 25%

Mrs. Canal is type A and Mr. Canal is type O. They have three children named Greg, Rosalind and Biff. Greg is type 0, Rosalind is type A and Biff is type AB...
Can BIFF be there son? Explain
Yes because he has a portion of A in his blood like his mom
Yes because his dad is type O and that is a universal donor
No because his sister is type A blood
No because neither parent has the B allele
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.
Complete a punnett square and then answer the question. What is the mother's genotype? What is the father's genotype?
Mom genotype is IᴬIᴬ, Dad genotype is IᴬIᴮ
Mom genotype is ii, Dad genotype is IᴮIᴮ
Mom genotype is ii Dad genotype is IᴬIᴮ
Mom genotype is ii Dad genotype is ii
Two parents think THEIR baby was switched at the hospital. Lulu (mom) has blood type A, and Caesar (dad) has blood type B. The baby has blood type AB. Could the baby actually be theirs?
No, because neither parent's genotype matches the baby
No because the mom is only Type A
Yes because both parents have type A and Type B
Yes because if mom is A and dad is B - the baby could have genotype AB
How many offspring are in the second generation?
