A survey was taken to determine the blood types of children from marriages in which the wife had the blood group AB and the husband had blood type A but one of his parents is type O. The survey resulted in 250 type A, 90 type B, and 110 type AB children. Is the deviation from the expected significant?
A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh positive is a trait that shows simple dominance over Rh negative and is designated by the alleles R and r, respectively. A third gene for the MN blood group has codominant alleles M and N. If both children are of blood type M in addition to their ABO blood type, list all of the possible parental phenotypes for the ABO, MN and Rh traits.
Karen and Steve each have a sibling with sickle-cell disease.Neither Karen nor Steve nor any of their parents have thedisease, and none of them have been tested to see if they carrythe sickle-cell allele. Based on this incomplete information,calculate the probability that if this couple has a child, thechild will have sickle-cell disease.
The ABO blood group is one set of blood antigens. Ther is a separate locus (H) that controls the presentation of these antigens on the cell surface. Individuals who are homozygous, hh, cannot present the antigens of the ABO type (and appear to be O-type). Consider the following cross: P0: IAi Hh x IBi Hh a. What is this type of inheritance pattern called? b. Complete the Punnett square to determine the phenotypic frequencies of the apparent blood groups among the offspring:
A man with the II (A) blood group and a woman with the III (B) blood group in the AB0 system have black hair. Their child has blond hair and the I (0) blood group. What is the probability of the birth of a child with the father’s phenotype?
ABO blood type is determined by three alleles: *, 18, and i. On a separate chromosome, anotherset of alleles determines the Rhesus factor: D and d.A woman with blood type A, who is heterozygous for both blood type and Rhesus factor, had achild with a man with blood type B, who is heterozygous for both blood type and Rhesus factor. What is the percentage chance that this child is blood type B and heterozygous for both traits? Record your answer as a percentage rounded to one decimal place.
Suppose two parents are healthy carriers of the sickle cell allele. The genotype of each parent is HbAHbS (HbAis the normal allele, and HbS is the sickle-cell allele).How likely is it for a child of these parents to have sickle cell anemia (HbSHbS)?
Which blood type phenotypes (A, B, AB, and/or O) provide anunambiguous genotype? Is it possible for a couple to produce afamily of children in which all four blood types are represented? Ifso, what would the genotypes of the parents have to be?
A woman homozygous for normal height, with freckles, almond-shaped eyes, small nose, and Type A blood, has a Type O mother with no freckles and a type AB father with round eyes. She is engaged to a man with achondroplasia, round eyes and medium sized nose. Unlike his father, hismother is of normal height. Both his parents have Type O blood but nobody from both sides of his family has or had freckles. a. Write the COMPLETE genotypes of the man and the woman. Clearly indicate which genotype belongs to whom. b. Based on their genotypes, what is the probability that they will have: b.1 a child with Achondroplasia? b.2 a child of normal height? b.3 a child with type AB blood? b.4 a daughter with round eyes, freckles, and medium sized nose? b.5 a son with almond eyes, no freckles, and small nose?b.6 a daughter with same genotype as the woman? b.7 a son with same genotype as the man?
Shown above is a family pedigree tree in which family members afflictedwith the disease Haemophilia are shown with filled-in squares (male) or circles (females). A couple is trying to determine the likelihood of passingon the disease to their future children (represented by the ? symbolabove) because the hemophilia runs in the woman’s family. Turner syndrome is a disease in which an individual is bornwith only a single X chromosome. Suppose the woman in thecouple is a carrier for hemophilia and has a child with Turnersyndrome. Would this child have the disease?
Joanne has AB blood and Henry has AB blood. They have one child with A blood, one child with AB blood, and another child that has O Bombay phenotype blood. Please explain what is happening here. What is the chance that Joanne and Henry will have a child with B blood type? What is the name of the phenomenon that is responsible for the Bombay phenotype?
In Table 2-1, state the recessive phenotype in each of theseven cases.
