What is the definition of incomplete dominance?

Back

Incomplete dominance is 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.

What is the definition of a phenotype?

Back

A phenotype is the physical appearance or observable characteristics of an organism, determined by its genotype.

Front

What is the definition of a genotype?

Back

A genotype is the genetic constitution of an individual, represented by the alleles inherited from its parents.

Front

What is codominance?

Back

Codominance is 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 the definition of a dominant allele?

Back

A dominant allele is an allele that expresses its phenotype even when only one copy is present in the genotype.

Front

What is the definition of a recessive allele?

Back

A recessive allele is an allele that only expresses its phenotype when two copies are present in the genotype.

What is the expected phenotypic ratio of a monohybrid cross?

Back

The expected phenotypic ratio of a monohybrid cross is 3:1.

What is the expected genotypic ratio of a monohybrid cross?

Back

The expected genotypic ratio of a monohybrid cross is 1:2:1.
