Sickle cell anemia shows autosomal recessive inheritance. In areas where malaria is endemic, heterozygous individuals show increased resistance to malaria resulting in the recessive allele being present at a higher frequency than would otherwise be expected. What type of natural selection is acting in malaria endemic regions?

SMAD4 is a tumor suppressor gene located on chromosome 18 that often shows reduced gene expression in human lung cancer. You perform a microarray using tissue from a normal person (green) and a lung cancer patient (red). What ratio of red to green fluorescence would you expect for SMAD4 gene expression if the patient’s tumor shows reduced SMAD4 gene expression?        

Most viruses cannot be seen by light microscopy.
