What are alleles?

Back

Alleles are different forms of a gene that can exist at a specific locus on a chromosome.

What does 'Homozygous' mean?

Back

Homozygous refers to having two identical alleles for a particular gene, such as 'AA' or 'aa'.

Front

What does 'Heterozygous' mean?

Back

Heterozygous refers to having two different alleles for a particular gene, such as 'Aa'.

What is a recessive allele?

Back

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