Codominance and Incomplete dominance

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is incomplete dominance?

Back

A genetic scenario where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What is a genotype?

Back

The genetic constitution of an individual, represented by the alleles inherited from the parents.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What are alleles?

Back

Different forms of a gene that can exist at a specific locus on a chromosome.

Front

What is the significance of the ABO blood group system?

Back

It is a classic example of codominance and multiple alleles, where the presence of A and B alleles can result in four blood types: A, B, AB, and O.

Front

What is the genotype for type B blood?

Back

I^B I^B or I^B i.

Front

What is the genotype for type A blood?

Back

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

Front

What is the genotype for type AB blood?

Back

I^A I^B.

Front

What is the genotype for type O blood?

Back

ii.
