Types of Dominance Practice Activity

Front

What is incomplete dominance?

Back

A type of inheritance where the heterozygote shows a phenotype that is a blend of the two parental traits.

Front

What is codominance?

Back

A type of inheritance where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that shows both traits distinctly.

Front

Give an example of incomplete dominance.

Back

The pink color of a carnation flower resulting from the blending of red and white parental flowers.

Front

What is complete dominance?

Back

A type of inheritance where one allele completely masks the effect of another allele in a heterozygote.

Front

What is the phenotype of a heterozygous organism in incomplete dominance?

Back

A blended phenotype that is different from both homozygous parents.

Front

How does codominance differ from incomplete dominance?

Back

In codominance, both traits are fully expressed, while in incomplete dominance, the traits blend.

Front

What type of dominance is shown in a calico cat?

Back

Codominance, as it displays both orange and black fur traits.

Front

What happens when a long-hair rabbit is crossed with a short-hair rabbit?

Back

The offspring exhibit medium-length hair, demonstrating incomplete dominance.

Front

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

Back

The offspring will show the dominant trait if complete dominance is present.

Front

What is a heterozygous genotype?

Back

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