There is debate as to whether the relationship between the alleles for normal blood and sickle cell anemia should be viewed as having a complete dominance relationship or a co-dominance relationship. Explain both view points. (In your answer define the terms complete dominance and co-dominance).

8) There is a blood type gene with three alleles A, B and O. A is dominant to O, B is dominant to O and A and B are co-dominant/incompletely dominant. What are the likely genotypes if a mother has the genotype AA and the father has the genotype BO? Group of answer choices a) 50% AA 50% BB b) 50% Ab blood 50% A blood c) 25% AB, 25% AO, 50% OO d) 50% AB 50% AO 9) There is...

explain, in detail, the relationship between malaria and sickle-cell anemia. Why is having one sickle-cell allele considered a selective advantage? Is this equally beneficial for someone who is homozygous recessive for sickle-cell? Why or why not? Note: use specific vocabulary to describe your answers (genotype, homozygous d, homozygous r, natural selection, heterozygous, etc)

6. Sickle cell anemia (disease) is described as an autosomal recessive condition (individuals must have two copies of the recessive allele to display “sickle cell disease”). However, sickle cell trait (the heterozygous condition) has a unique phenotype. a. How would you classify/describe sickle cell trait at the organismal level (complete, incomplete, or co-dominance)? Explain your reasoning. b. How would you classify/describe sickle cell trait at the molecular level (complete, incomplete, or co-dominance)? Explain your reasoning. (HINT: think about the hemoglobin...

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...

A woman has a father with sickle-cell anemia, which is an autosomal recessive trait. She does not have symptoms of sickle-cell anemia. What is her genotype? (0.5 marks) b) She is about to start a family, and she knows that her partner’s mother has sickle-cell anemia, but he does not have the disease himself. What is the probability of them having a child with sickle-cell anemia? Demonstrate this using a Punnett square. (2.5 marks) c) If they have three children,...

LOUISE Homework Quizzes & Tests A gene is composed of two alleles. An allele can be either dominant or recessive. Suppose that a rusband di wile, allele but do not have the disease, decide to have a child. Because both parents are carriers of the disease, each has one dominant normal-cell allele (S) and one recessive sickle-cell allele (s). Therefore, the genotype of each parent is Ss. Each parent contributes one allele to his or her offspring with each allele...
