50 percent is the correct answer . Because the chance of being female or male is 50 percent. If the child born is a boy then the boys will be normal because it is through x chromosome of father transmits the disorder and if the child born is a girl then the girl is a carrier of the disorder because the male child will contain normal x chromosome from mother and the defective x chromosome from father.

Use the following information to answer the next two questions. Sickle cell anemia is a disease that is caused by a mutation in the gene that produces haemoglobin. Hemoglobin carries oxygen in red blood cells. The HbA allele produces normal hemoglobin and the HbS allele produces haemoglobin that sticks together and causes red blood cells to sickle. Heterozygous individuals (HbAHbS) produce both normal and "sickle" hemoglobin so the HbA and HbS alleles are codominant. Heterozygotes do not develop sickle cell...

Sickle Cell Anemia Sickle cell anemia is the result of a type of mutation in the gene that codes for part of the hemoglobin molecule. Recall that hemoglobin carries oxygen in your red blood cells. The mutation causes these red blood cells to become stiff & sickle-shaped when they release their oxygen. The sickled cells tend to get stuck in blood vessels, causing pain and increased risk of stroke, blindness, damage to the heart & lungs, and other conditions. Analyze...

5. Sickle-cell disease is an interesting genetic disease. Normal homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become very ill from the parasite and many die. Individuals homozygous for the sickle-cell trait (ss) have red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the genetic defect. However, individuals with the heterozygous condition (Ss) have some...

Sickle-cell Anemia Study Sickle-cell anemia or Sickle-cell disease, is a hereditary disorder. characterized by aryabnormality in the oxygen-carrying hemoglobin molecule in erythrocytes. Sickle-cell conditions have an autosomal recessive pattern of inheritance from parents. The sickle cell defect is a mutation of a single nucleotide of the hemoglobin B gene, which results in glutamic acid being substituted by a different amino acid at position 6. Hemoglobin with this mutation is referred to as Hbs, as opposed to the normal hemoglobin HbA....

3. Sickle-cell disease is a genetic condition caused by an autosomal recessive allele which al- fects one in every 500 African American children born in the U.S. One in every ten African Americans is a carrier for the recessive allels. Although sickle cell disease is caused by a single human gene, it is expressed through many different effects throughout the body. The presence of a recessive sickle-cell allele in humans causes the red blood cells to produce abnormal hemoglobin protein...

Which of the following statements about sickle cell anemia is INCORRECT? Select one: a.

Two parents come to see you for genetic counseling. Dad is sickle cell carrier (sickle cell is a recessive genetic disease) and has a normal cholesterol. Mom is also a carrier for sickle cell and has struggled with high cholesterol, and a test by her doctor recently showed that she is heterozygous for hypercholesterolemia (hypercholesterolemia is a genetic disease that shows incomplete dominance). What are the odds of them producing a child with sickle cell disease?-------A child who is a...
