Review Genetics

Homozygous means having two identical alleles for a trait, while heterozygous means having two different alleles.

Homozygous means having two different alleles for a trait, while heterozygous means having two identical alleles.

Homozygous refers to a single allele for a trait, while heterozygous refers to two alleles of the same type.

Homozygous and heterozygous are terms that describe the same genetic condition.

A recessive trait is expressed only when one copy of the recessive allele is present (e.g., 'Tt').

A recessive trait is expressed only when two copies of the recessive allele are present (e.g., 'tt').

A recessive trait is always expressed regardless of the allele combination.

A recessive trait is expressed when it is paired with a dominant trait.
