Incomplete Dominance vs. Co-Dominance

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 Co-Dominance?

Back

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

Front

Example of Incomplete Dominance?

Back

When a red flower is crossed with a white flower, resulting in pink flowers.

Front

Example of Co-Dominance?

Back

A calico cat showing both orange and black fur.

Front

How does Incomplete Dominance differ from Mendelian inheritance?

Back

In Incomplete Dominance, the heterozygous genotype results in a unique phenotype, unlike Mendelian inheritance where dominant alleles mask recessive ones.

Front

How does Co-Dominance differ from Mendelian inheritance?

Back

In Co-Dominance, both alleles are expressed equally in the phenotype, unlike Mendelian inheritance where one allele is dominant.

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 heterozygous genotype?

Back

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

Front

What is a homozygous genotype?

Back

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