Incomplete Dominance and Codominance

Front

What is the definition of phenotype?

Back

Phenotype refers to the observable physical characteristics or traits of an organism, such as height, color, and shape.

Front

What is the definition of genotype?

Back

Genotype refers to the genetic makeup of an organism, specifically the alleles it possesses for a particular trait.

Front

What is incomplete dominance?

Back

Incomplete dominance is a type of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What is codominance?

Back

Codominance is a type of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits.

Front

Give an example of codominance.

Back

An example of codominance is a calico cat, which has both orange and black fur.

Front

Give an example of incomplete dominance.

Back

An example of incomplete dominance is when a red flower and a white flower produce pink flowers.

Front

What does BB represent in genetics?

Back

BB represents a homozygous genotype for a trait, where both alleles are the same.

Front

What does blonde represent in genetics?

Back

Blonde represents a phenotype, which is the observable trait of hair color.

Front

What is the result of crossing a black chicken with a white chicken in codominance?

Back

The result would be black and white checkered chickens.

Front

What is the difference between phenotype and genotype?

Back

Phenotype is the physical expression of traits, while genotype is the genetic code that determines those traits.
