| Description: |
In genetics, a test-cross is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous for that trait. This is done by crossing (breeding) that individual (whose genotype is unknown) with an individual which is known to be homozygous recessive for that particular trait.
