What else can I help you with?
Which person on the pedigree could not pass the allele for sickle cell disease to his her offspring?
V
Can a person who has been successfully treated for sickle cell disease still transmit the disease-causing allele to offspring?
Sickle-cell anemia can only be transmitted if both partners have the disease.
Is sickle cell disease dominant or recessive?
The disease is recessive, requiring both parents to carry the allele for the disease to be found in the offspring. If one parent has it, the offspring can also be a carrier, but it will be recessive, and the offspring will have normal RBC (red blood cells)
For sickle-cell disease assume S is the dominant allele and s the recessive allele Which genotypes are possible for offspring of a carrier (Ss) and a person who lacks the sickle-cell allele (SS)?
SS,Ss
What groups get sickle cell disease?
A person can only inherit sickle-cell genes if some of their ancestors came from certain regions in Africa where the inhabitants carry sickle-cell genes. A person with one sickle-cell gene has sickle-cell trait, a milder problem. If both father and mother pass on sickle-cell genes, the child, with two genes, will have sickle-cell disease.
What is require for a person to have sickle-cell disease?
The person is homozygous for the trait
Are sickle cell anemia and sickle cell trait the same?
No, sickle cell anemia and sickle cell trait are not the same. Sickle cell anemia is a severe form of the disease caused by inheriting two sickle cell genes (one from each parent), leading to significant health complications. In contrast, sickle cell trait occurs when an individual inherits only one sickle cell gene and one normal gene, typically resulting in no symptoms but allowing the person to pass the trait to their offspring.
How is sickle cell trait different from sickle cell disease and what are the key distinctions between the two conditions?
Sickle cell trait and sickle cell disease are both genetic conditions caused by a mutation in the hemoglobin gene. Sickle cell trait means a person carries one copy of the mutated gene, while sickle cell disease means a person has two copies. The key distinction is that individuals with sickle cell trait usually do not experience symptoms, while those with sickle cell disease can have severe health issues such as pain crises, anemia, and organ damage.
How does a person with one sickle cell different than two Sickle cell?
A person with one sickle cell is a "carrier". This means that they have the dormant cell in their genetic composition, and if combined with another with the "carrier" gene, they run the high risk on concieving a child with the blood disease-one who has two sickle cells. A person with two sickle cells, has the sickle cell disease and are carriers(The gene is not dormant but active). Hope this simplifies and explains it for you.
What is requires for a person to have sickle cell disease?
The person is homozygous for the trait
Is sickle cell disease a blood cancer?
No, sickle cell disease is not cancerous.
Is you kiss do you get sickle cell disease?
No. Sickle Cell is not an infectious disease, but is genetic.
