A man and a woman living in a tropical area where malaria is prevalent and health care is not accessible have seven children during their lifetime. The genotypes of their children are: ss, Ss, SS, ss, Ss, Ss, and SS. What must the genotypes of both parents be? Your answer should include a Punnett square to illustrate your work, and list all the genotypes and phenotypes.

Background information for problem #5 In humans there is a gene that controls formation of hemoglobin (the protein in red blood cells {RBC's} that is responsible for carrying oxygen to the tissues of the body). The normal allele of this gene codes for normal hemoglobin. However, there is another allele for this gene that contains a mutation in the DNA and the resulting hemoglobin protein is defective. An RBC with this defective hemoglobin will, under stress, crystallize within the cell and cause a characteristic sickle shape. While the letters S and s are often used to represent these alleles, in reality neither is dominant to the other (codominant). Someone who is SS makes all normal hemoglobin, someone who is ss makes all abnormal hemoglobin (someone who has sickle-cell anemia), and someone who is Ss essentially has two sets of instructions (and so makes some of each kind of hemoglobin; often referred to as sickle-cell trait). Because the RBC's of a person who is ss contain all…
2) You're the director of Foothill Presbyterian Hospital's maternity ward, and you have four mixed-up babies, with blood types of O, A, B, and AB. The four sets of desperate parents are threatening to sue you if you don't get their babies back. You know the blood types (phenotypes) of the parents are: i) AB and O ii) A and O iii) A and AB iv) O and O You also know that each set of parents has only one child (no sets of twins, that is). Match each baby with its parents.
A man of blood group B is being sued by a woman of blood group A for paternity. The womans child is blood group O.a) If this man is actually the father of this child, specify the genotypes of both parents?b) If it was impossible for this group B man to be the father of a type O child, specify his genotype?c) If a man was blood group AB, could he be the father of group O child?
IX. The blood of several members of a particular family was determined, and the results are tabulated below. Individual Blood Type Genotype Father Mother B Child 1 AB Child 2 B. Child 3 Grandfather (mother's side) Grandmother (father's side) AB Assuming that no adultery or adoption took place for all generations, answer the following questions: a. Give the most probable genotype for each individual. Supply your answers on the table above. b. What is/are the most probable genotype(s) for the grandmother on the mother's side? c. If the father and the mother decide to have two more children, what is the probability that the first would be female type A and the second male type AB?

1.) A student recently told me that both she and her brother have blue eyes (bb), and that both of her parents are brown-eyed. Using a Punnett square, list the genotypes and phenotypes showing how it's possible for this to happen.
A man of blood group A is being sued by a woman of blood group B for paternity. The women’s child is blood group O. A) Is this man the father of this child? Explain. B) If this man actually is the father of this child, specify the genotypes of both parents. C.) If it was impossible for this group A man to be the father of a type O child, regardless of the mother’s genotype, specify his genotype. D.) If a man was blood group AB, could he be the father of a group O child? Why/why not?
Codominance ABO blood typing is an example of codominance, where A and B are both dominant to O. A woman who is AB type has a child with a man who is O type. Use I allele formatting to designate each genotypes: IA IA, IA i, IB IB, IB i, IA IB, ii A) List the genotype of each parent. B) Complete a Punnett square. List all the genotypes for the predicted offspring of this mating (using the format of genotypes listed above) C) What is the probability that any of their offspring will be O type? D) What is the probability that any of their offspring will be AB type?

Cystic Fibrosis (CF) is an autosomal recessive condition. Therefore, heterozygous (Cc) carriers do not display symptoms. Two parents who are carriers plan to start a family and you are a genetic counselor helping to advise them about their chances of having children affected by CF. a) Suppose the couple has 4 children, each one year apart. What is the probability that all 4 children will inherit CF? b) What is the probability that any 3 of their 4 children will not inherit CF, but 1 will be affected? c) What is the probability that their first child will not inherit CF, but the younger 3 children will inherit CF?
