I was always facinated by the sickle-cell anemia (disease) situation. Meaning if you have both recessive alleles you will have the disease but will be immune to malaria. But you may not live long because of the disease. If you are a heterozygote you are relatively immune to malaria and have mild symptoms of sickle-cell anemia. If you do not have sickle-cell anemia (i.e. healthy) you are extremely suseptable to getting malaria. You tend to have a high ammount of heterozygous geneotypes in areas that have high levels of malaria carrying mosquitos. -Mike -References: Any basic genetics text book.
