Incomplete Dominance Codominance

Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype that is a blend of the two traits.

Front

What is codominance?

Back

A genetic situation in which both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that shows both traits.

Front

Give an example of incomplete dominance.

Back

A red flower crossed with a white flower produces pink flowers.

Front

Give an example of codominance.

Back

A calico cat shows both orange and black fur, expressing both traits.

Front

What is the result of a cross between two homozygous parents with different traits in incomplete dominance?

Back

The offspring will have a phenotype that is a blend of the two parental traits.

Front

What is the result of a cross between two heterozygous parents in codominance?

Back

The offspring will express both parental traits simultaneously.

Front

How does incomplete dominance differ from complete dominance?

Back

In complete dominance, one allele completely masks the effect of another, while in incomplete dominance, both alleles contribute to the phenotype.

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 for a particular gene.

Front

What is an allele?

Back

An alternative form of a gene that can produce different traits.
