Substitution.

Front

What is a dominant trait?

Back

The trait that will always be expressed if one copy of an allele is present.

Front

What is a phenotype?

Back

The observable physical expression of a trait, such as blue eyes.

Front

What is an allele?

Back

A variant form of a gene that can produce different traits.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even when only one copy is present, while recessive alleles require two copies to express their trait.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in traits.

Front

What is co-dominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed.

Front

What is a homozygous genotype?

Back

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