ne, seizures, poor muscle tone, and progressive kidney failure which was ultimately fatal. His older sister Lily prompted a pedigree analysis. She remembers a doctor saying that her mother, Drucilla is a carrier and her ather James is assumed to be normal. Lily is married to Arthur, which is also assumed to be unaffected by he disease. They have 1 daughter named Kristy. After cytogenetic analysis, Lily's physician determined that she is a carrier. She asked her physician whether her daughter will be affected by the disease that killed her rother. Her doctor told her not to worry about the disease affecting her daughter. Based on the case scenario presented above, answer the following questions. 1. Make a pedigree chart that will represent Lily's family, from her parents to her daughter. Use the symbols provided in Module 4 as your guide. Indicate the generations using roman numerals, and individuals in a generation using arabic numerals. Male partners should be to the left of female partners on a relationship line. Siblings should be listed from left to right in birth order (oldest to youngest).

In individuals affected by cystic fibrosis, salt crystals may appear afterperspiration dries up. In addition, the disease causes respiratory disorderswhich can be both debilitating and lethal. It occurs in individuals homozygousfor the recessive gene. Two normal parents had a daughter with thesymptoms of this disease, and a normal son who marries a normal womanwith an afflicted A test (salt concentration in perspiration of heterozygotes ishigher than normal) disclosed that both are indeed carriers of the gene. If thefirst child born to the mating in (b) was defective, what is the probability thatthe 2nd child would also be defective?Express answer in fraction form
Construct pedigree charts using the inheritance of hemophilia in figure 92 (page 113). This is X-linked inheritance so you are required to label XX for females and XY for males. The gene responsible for the trait is represented by the superscript which should be specified in the legend.
The mother of a family with 10 children has blood typeRh+. She also has a very rare condition (elliptocytosis,phenotype E) that causes red blood cells to be oval rather than round in shape but that produces no adverseclinical effects. The father is Rh− (lacks the Rh+ antigen)and has normal red blood cells (phenotype e). The children are 1 Rh+ e, 4 Rh+ E, and 5 Rh− e. Information isavailable on the mother’s parents, who are Rh+ E andRh− e. One of the 10 children (who is Rh+ E) marriessomeone who is Rh+ e, and they have an Rh+ E child.a. Draw the pedigree of this whole family.b. Is the pedigree in agreement with the hypothesisthat the Rh+ allele is dominant and Rh− is recessive?c. What is the mechanism of transmission ofelliptocytosis?d. Could the genes governing the E and Rh phenotypesbe on the same chromosome? If so, estimate the mapdistance between them, and comment on your result
In humans, a rare dominant disorder known as nail-patella syndromecauses abnormalities in the fingernails, toenails, and kneecaps.Researchers have examined family pedigrees with regard to thisdisorder and have also examined the blood types of individualswithin each pedigree. (A description of blood genotypes is foundin Chapter 4.) In the following pedigree, individuals affected withnail-patella disorder are shown with filled symbols. The genotypeof each individual with regard to ABO blood type is also shown.Does this pedigree suggest any linkage between the gene thatcauses nail-patella syndrome and the gene that causes blood type?
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?

In 1995, doctors reported a Chinese family in whichretinitis pigmentosa (progressive degeneration of theretina leading to blindness) affected only males. Allsix sons of affected males were affected, but all of thefive daughters of affected males (and all of thechildren of these daughters) were unaffected.a. What is the likelihood that this form of retinitispigmentosa is due to an autosomal mutationshowing complete dominance?b. What other possibilities could explain the inheritance of retinitis pigmentosa in this family? Whichof these possibilities do you think is most likely?
A cross was performed between a female curly winged fly and a normal (straight) winged male fly. Curly wing is known to be recessive. The results were 42 straight winged and 39 curly winged flies. From his date determine the genotypes of the P1generation using the letter A.
