incomplete and codominance

Front

What is Incomplete Dominance?

Back

A genetic scenario where one allele is not completely dominant over another, resulting in a blended phenotype in heterozygous offspring.

Front

What is Codominance?

Back

A genetic scenario where both alleles in a heterozygous individual are fully expressed, resulting in offspring with a phenotype that shows both traits.

Front

How does Incomplete Dominance differ from Codominance?

Back

In Incomplete Dominance, the traits blend together, while in Codominance, both traits are distinctly expressed.

Front

What is a heterozygous genotype?

Back

A genotype consisting of two different alleles for a particular gene.

Front

Give an example of Incomplete Dominance.

Back

An example is the flower color in snapdragons, where red and white flowers produce pink flowers in the offspring.

Front

Give an example of Codominance.

Back

An example is the ABO blood group system, where both A and B alleles are expressed in individuals with AB blood type.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

The genetic constitution of an individual, specifically the alleles present at a given locus.

Front

What is a Punnett square?

Back

A diagram used to predict the outcome of a particular cross or breeding experiment, showing the possible genotypes of offspring.

Front

What does it mean for an allele to be dominant?

Back

An allele that expresses its phenotype even when heterozygous with a recessive allele.
