Recessive traits like sickle cell disease can be relatively common in certain populations due to a phenomenon known as heterozygote advantage. Individuals with one copy of the sickle cell allele (heterozygotes) have some protection against malaria, which enhances their survival and reproductive success in malaria-endemic regions. This advantage allows the recessive allele to persist in the gene pool, even though individuals with two copies of the allele (homozygotes) may experience severe health issues. Therefore, the prevalence of such traits can be linked to environmental factors and selective pressures.
What else can I help you with?
Is sickle cell anemia recessive or dominant?
Sickle cell anemia is an autosomal recessive disease. Carriers have sickle cell trait, which confers resistance to malaria.
Is sickle cell disease a chromosomal abnormality?
sickle cell is an autosomal recessive disorder
Is sickle cell an dominant or recessive?
Sickle cell anemia is an autosomal recessive disorder. It can result from two carriers having a child together.
What is the genotype of a man who has sickle cell trait?
rr since sickle cell is a recessive trait.
Is sickle cell anemia genetic or environmental?
Sickle cell anemia is genetic. It is an autosomal recessive disease.
Is sickle cell anemia dominant or receive?
recessive
What is the inheritance of the sickle cell anemia?
autosomal recessive
What is an inherited autosomal recessive disorder of the blood where an individuals red blood cells are sickle shaped rather than disk shaped?
C. Sickle-cell anemia
What is the method of transmission of the sickle cell gene?
autosomal recessive
What is the mode of inheritance for sickle-cell anemia?
autosomal recessive
Give an example of a recessive traits?
In humans good examples are blue eyes, blonde hair, type "O" blood, sickle cell anemia, and hemophilia.
What is it called when a person has two recessive alleles for sickle cell trait?
A person with two recessive alleles for sickle cell trait has sickle cell anemia. This genetic condition leads to the production of abnormal hemoglobin, causing red blood cells to become sickle-shaped and leading to various health issues.
