Non-Mendelian Genetics Daily Quiz

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.

Which of the following is an example of a gene with multiple alleles in rabbits?

• Eye color gene

• Fur color gene

• Ear size gene

• Tail length gene

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
