Several genes in humans in addition to the ABO gene () give rise to recognizable antigens on the surface of the red blood cells. TheRh marker is determined by positive (R) and negative alleles () of gene R, where R is completely dominant to r. The presence of M andN surface proteins are controlled by two codominant alleles of gene L (LM and LM. For each mother-child pair, choose the father ofthe child from among the males in the right column. (Assume that all mothers and fathers are HH; there is no involvement of theBombay phenotype.)Paternal genotypes maybe used once, more than once, or not at all.

The Mic2 gene in humans is present on both the X and Y chromosome. Let’s suppose the Mic2 gene exists in a dominant Mic2 allele, which results in normal surface antigen production, and arecessive mic2 allele, which results in defective surface antigenproduction. Using molecular techniques, it is possible to distinguish homozygous and heterozygous individuals. By followingthe transmission of the Mic2 and mic2 alleles in a large human pedigree, would it be possible to distinguish between pseudoautosomalinheritance and autosomal inheritance? Explain your answer
The XG locus on the human X chromosome has twoalleles, XG+ and XG. The XG+ allele causes the presence of the Xg surface antigen on red blood cells,while the recessive XG allele does not allow antigento appear. The XG locus is 10 m.u. from the STSlocus. The STS+ allele produces normal activity ofthe enzyme steroid sulfatase, while the recessive STSallele results in the lack of steroid sulfatase activityand the disease ichthyosis (scaly skin). A man withichthyosis and no Xg antigen has a normal daughterwith Xg antigen. This daughter is expecting a child.a. If the child is a son, what is the probability he willlack Xg antigen and have ichthyosis?b. What is the probability that a son would have boththe antigen and ichthyosis?c. If the child is a son with ichthyosis, what is theprobability he will have Xg antigen?
Duchenne muscular dystrophy is sex linked and usuallyaffects only males. Victims of the disease become progressively weaker, starting early in life.a. What is the probability that a woman whose brotherhas Duchenne’s disease will have an affected child?b.

If your father’s brother had the disease, what is theprobability that you have received the allele?
. The production of pigment in the outer layer of seedsof corn requires each of the three independently assorting genes A, C, and R to be represented by at leastone dominant allele, as specified in Problem 64. Thedominant allele Pr of a fourth independently assortinggene is required to convert the biochemical precursorinto a purple pigment, and its recessive allele pr makesthe pigment red. Plants that do not produce pigmenthave yellow seeds. Consider a cross of a strain of genotype A/A ; C/C ; R/R ; pr/pr with a strain of genotypea/a ; c/c ; r/r ; Pr/Pr.a.

. For several years, Hans Nachtsheim investigated an inherited anomaly of the white blood cells of rabbits. Thisanomaly, termed the Pelger anomaly, is the arrest ofthe segmentation of the nuclei of certain white cells. Thisanomaly does not appear to seriously burden the rabbits.a. When rabbits showing the Pelger anomaly were matedwith rabbits from a true-breeding normal stock,Nachtsheim counted 217 offspring showing the Pelgeranomaly and 237 normal progeny. What is the geneticbasis of the Pelger anomaly?b. When rabbits with the Pelger anomaly were matedwith each other, Nachtsheim found 223 normal progeny,439 with the Pelger anomaly, and 39 extremely abnormalprogeny. These very abnormal progeny not only haddefective white blood cells, but also showed severedeformities of the skeletal system; almost all of themdied soon after birth. In genetic terms, what do yousuppose these extremely defective rabbits represented?Why were there only 39 of them?c. What additional experimental evidence…

Spherocytosis is an inherited blood disease in whichthe erythrocytes (red blood cells) are spherical insteadof biconcave. This condition can be inherited in adominant fashion, with ANK1 (the nonfunctional mutant allele) dominant to ANK1+. In people with spherocytosis, the spleen recognizes the spherical redblood cells as defective and removes them from thebloodstream, leading to anemia. The spleen in different people removes the spherical erythrocytes withdifferent efficiencies. Some people with sphericalerythrocytes suffer severe anemia and some mild anemia, yet others have spleens that function so poorly nosymptoms of anemia exist at all. When 2400 peoplewith the genotype ANK1 ANK1+ were examined, itwas found that all of them had spherical erythrocytes,2250 had anemia of varying severity, and 150 had nosymptoms. (Assume that ANK1 ANK1 homozygotesdo not exist.)a. Does this description of people with spherocytosisrepresent incomplete penetrance, variable expressivity, or both? Explain…
. Among adults with Turner syndrome, it has beenfound that a very high proportion are genetic mosaics.These are of two types: In some individuals, themajority of cells are XO, but a minority of cellsare XX. In other Turner individuals, the majorityof cells are XO, but a minority of cells are XY.Explain how these two patterns of somatic mosaicscould arise.
Familial retinoblastoma, a rare autosomal dominant defect, arose in a large family that had no prior history of the disease. Consider the following pedigree (the darkly colored symbols represent affected individuals): a. Circle the individual(s) in which the mutation most likely occurred. b. Is the person who is the source of the mutation affected by retinoblastoma? Justify your answer. c. Assuming that the mutant allele is fully penetrant, what is the chance that an affected individual will have an affected child?
The ABO blood groups in humans are expressed as the IA,IB and i alleles. The IAallele encodes the A blood group antigen, IB encodes B, and i encodes O. Both A and B are dominant to 0. If a heterozygous blood type A parent (IAi) and a heterozygous blood type B parent (IBi) mate, one quarter of their offspring are expected to have the AB blood type IAIBin which both arnigens are expressed equally. Therefore, ABO blood groups are an example of: a. multiple alleles and incomplete dominance b. codominance and incomplete dominance c. incomplete dominance only d. multiple alleles and codominance
Several genes in humans in addition to the ABO gene(I) give rise to recognizable antigens on the surface ofred blood cells. The MN and Rh genes are two examples. The Rh locus can contain either a positive or anegative allele, with positive being dominant to negative. M and N are codominant alleles of the MN gene.The following chart shows several mothers and theirchildren.
