Incomplete and Codominance

Front

What is incomplete dominance?

Back

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

Front

What is codominance?

Back

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

Front

What is the phenotype of a heterozygous radish with red and white pure breeding parents?

Back

Purple, due to incomplete dominance.

Front

What are the possible genotypes for blood type B?

Back

I^B I^B and I^B i.

Front

What is the phenotype of blood type O?

Back

It doesn’t contain antigen A or antigen B.

Front

If a black chicken and a white chicken produce only checkered chickens, what inheritance pattern is this?

Back

Co-Dominance.

Front

What is the phenotype of a grey offspring from a black male and a white female?

Back

Grey, due to incomplete dominance.

Front

What is the genotype for blood type A?

Back

I^A I^A or I^A i.

Front

What is the genotype for blood type AB?

Back

I^A I^B.

Front

What is the phenotype of a homozygous red radish crossed with a homozygous white radish?

Back

All offspring will be purple due to incomplete dominance.
