One is called sickle cell anemia.

no there is no such thing as a straight sickle
Sickle-cell anemia is characterised by abnormal haemoglobin which are not the correct shape and cannot carry oxygen. It is a genetic disease - and a person must have two copies of the gene to have sickle-cell anemia. (Heterozygous individuals, with one copy, are known as having sickle-cell trait - and some of their haemoglobin may be misshapen).
Sickle cell disease is an autosomal recessive disorder, meaning that it is caused by a mutation in one of the autosomal chromosomes (chromosomes that are not sex chromosomes). In the case of sickle cell disease, the mutation occurs in the gene encoding the beta-globin subunit of hemoglobin on chromosome 11.
Sickle-Cell Disease
sickle cell trait is caused by two recessive alleles - meaning both partns must give resessive trait DNA o their child. - sickle cell anemia dose not have a benefit - or if it dose it is out waysd by the fact that people with sickle cell have very low blood oxygen as their blood cellsare dis-formed. however, if there is only one allele- ie they have A and b alleles for sickle cell. then they are more immune to malaria. a deadly parasite passed by misquotes in tropical countries.
