Mouse models for human genetic diseases are potentially powerful tools to help geneticists understand thecause of the aberrant phenotypes and develop newtherapeutic measures. However, such mice are not always as useful to investigators as it might seem at firstglance. Suppose that you have a mouse knockoutmodel for a human disease caused by homozygosityfor a null allele of a gene. Discuss how the followingsituations might complicate investigations of the human disease based on this mouse model.a. Mice have a shorter life span than humans.b. Mice homozygous for certain knockout mutationsdie in utero.c. Mouse genomes may have additional copies of thegene whose mutation causes the disease in humans.
