Incomplete Dominance and 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 where both alleles in a gene pair are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

Define Multiple Alleles.

Back

A situation in genetics where a gene has more than two alleles, leading to multiple possible phenotypes.

Front

What is Polygenic Inheritance?

Back

A pattern of inheritance where multiple genes influence a trait, resulting in a continuous range of phenotypes.

Front

What is the genotype of a person with type A blood?

Back

Possible genotypes are AA or AO.

Front

What is the genotype of a person with type B blood?

Back

Possible genotypes are BB or BO.

Front

What is the probability of a child having type O blood if both parents are type AB?

Back

0%.

Front

Give an example of a trait that exhibits Incomplete Dominance.

Back

Flower color in snapdragons, where red and white flowers produce pink offspring.

Front

Give an example of a trait that exhibits Codominance.

Back

Blood type AB, where both A and B alleles are expressed.

Front

What is the phenotype of a person with genotype Aa?

Back

The phenotype will depend on whether A is dominant or recessive.
