Non-Mendelian Genetics Daily Flashcard

Front

Codominance

Back

When two alleles are present and both are fully expressed

Front

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

Back

A person with type AB blood

Front

Incomplete dominance

Back

When the phenotype of the heterozygote is a blend of the two homozygous phenotypes

Front

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

Back

A snapdragon flower that is pink when a red and white flower are crossed

Front

What are multiple alleles?

Back

When a gene has more than two allele forms

Front

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

Back

Human blood types

Front

What is incomplete dominance in genetics?

Back

When an organism displays a phenotype that is somewhere between the two parental phenotypes

Front

What is the concept of multiple alleles in genetics?

Back

It is when there are more than two alleles for a gene in a population.

Front

Example of a gene with multiple alleles in rabbits: Eye color gene, Fur color gene, Ear size gene, Tail length gene

Back

Fur color gene

Front

What term is used to describe inheritance patterns that do not follow the Mendelian inheritance rules?
