The gene that causes Huntington’s chorea is an example of a lethal gene.A gene that, under certain conditions, causes the death of the individual carrying it. Lethal genes are usually recessive: an individual will die only if both his parents carry the gene. If only one parent is affected, the lethal effects of the gene will be masked by the dominant allele inherited from the normal parent have the lethal gene, its consequences will be masked by the dominant allele passed on by the normal parent.A gene that creates a condition incompatible with life and usually results in the death of the fetus.
