Homozygous and Heterozygous Genotype

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a particular gene (e.g., AA or aa).

Front

What is the difference between dominant and recessive alleles?

Back

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

Front

What is an allele?

Back

An allele is a variant form of a gene that can produce different traits.
