A researcher was performing a test to check the effect of induced point mutation. But the experimental mouse could not survive. The reason for this is a lethal mutation. This is a mutation in which the effects can result in the death of an organism carrying the mutation. It is also known as lethal factor or lethal gene.

I hope it helps, Regards.
