Front

Define Dominant Allele.

Back

An allele that expresses its phenotype even in the presence of a recessive allele.

TT

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the observable traits.

Front

What is Incomplete Dominance?

Back

A genetic situation where neither allele is completely dominant, resulting in a blend of traits.

Front

What is Co-Dominance?

Back

A genetic situation where both alleles are fully expressed in the phenotype.

Front

What are Alleles?

Back

Different versions of the same gene.

Front
