What is codominance?
When one allele hides the effect of another allele
When two alleles are present and both are fully expressed
When multiple alleles exist for a particular gene
When the phenotype is somewhere between two homozygous phenotypes
Which of the following is an example of codominance?
A pink flower resulting from a red and white flower
A person with type AB blood
A flower with multiple color petals due to multiple alleles
A snapdragon flower with an intermediate phenotype
What is incomplete dominance?
When the phenotype of the heterozygote is identical to the dominant homozygote
When the phenotype of the heterozygote is a blend of the two homozygous phenotypes
When a single gene has more than two alleles
When two alleles are fully expressed at the same time
Which of the following is an example of incomplete dominance?
A speckled chicken resulting from a black and white chicken
A person with type O blood
A snapdragon flower that is pink when a red and white flower are crossed
Blood types in humans
What are multiple alleles?
When a gene exists in only two allele forms
When a gene has more than two allele forms
When two alleles are expressed equally
When the phenotype is a mix of two alleles
Which of the following is an example of multiple alleles?
A red and white flower producing pink offspring
A black and white chicken producing speckled offspring
Human blood types
A pink snapdragon resulting from red and white parents
What is incomplete dominance in genetics?
When an organism displays a trait that is exactly like one of the parents
When an organism is not capable of inheriting any traits
When an organism displays a phenotype that is somewhere between the two parental phenotypes
When an organism fully expresses both alleles for a trait
What is the concept of multiple alleles in genetics?
It is when there are fewer alleles for a gene in a population.
It is when there are exactly two alleles for a gene in a population.
It is when there are more than two alleles for a gene in a population.
It is when a gene does not have any alleles in a population.

What term is used to describe inheritance patterns that do not follow the Mendelian inheritance rules?
Mendelian Inheritance
Non-Mendelian Inheritance
Simple Inheritance
Complex Inheritance
What is polygenic inheritance?
When a trait is controlled by a single gene
When a trait is controlled by multiple genes
When a trait is not controlled by genes
When a trait is controlled by environmental factors only
Which of the following is an example of a trait that is controlled by polygenic inheritance?
Blood type in humans
Presence of a tail in animals
Height in humans
Ability to roll one's tongue
Which of the following is another example of polygenic inheritance?
Eye color in humans
Wing color in butterflies
Beak shape in birds
Hair color in humans
