III. Write TRUE if the statement is correct and FALSE if otherwise. 7. A female parent possessing an X-linked dominant mutation is considered a carrier and will not manifest clinical symptoms of the disorder. 8. Y-linked traits are passed from the father to son, without the occurrence of genetic recombination. 9. Somatic mosaicism results to abnormalities based on the amount and distribution of normal cells while gonadal mosaicism affects the germline tissues leading to a new dominant mutation. 10. A test cross is done to determine which allele is dominant and which is recessive.

Explain the following1. A couple comes to a genetic councilor concerned about their chances of having a baby with cystic fibrosis disease. The husband had a sibling die of the disease. What are the chances that he is a carrier?
12. A. B. C. D. 9:24 A. .5G prairiestate.desire2learn.com does that prove ne is the father of the baby or the person who committed the crime? Explain your answer. Hemophilia is an x-linked disease in which the blood does not clot normally; it is sometimes called "bleeder's disease." Hemophilia is caused by a recessive allele (h). The dominant allele (H) produces blood that clots normally. What is genotype of a man who is a hemophiliac? What is the genotype of a man with normal blood clotting? What is the genotype of a woman with normal clotting blood if her father was a hemophiliac? If a man with normal clotting blood and a heterozygous woman have children together, what would you expect for the genotypes and phenotypes of the children? 13. A dominant x-linked allele (B) gives normal color vision but the recessive allele (b) causes red-green color blindness. What is the genotype of a man with normal color vision whose father was color- blind?
6. Hemophilia causes severe bleeding from minor wounds. The blood is unable to clot properly because one of the factors necessary for clotting is missing. Hemophilia is an inherited sex-linked recessive disorder transmitted on the X chromosome by mothers to their sons. i) A woman inherited the gene for hemophilia from her mother and marries a man who iş normal and has no hemophilia. What is the possibility that her children can have hemophilia?
8. Identify the following. Gene found on Y chromosome but not X chromosomes Protein coded for by SRY gene Function of testis determining factor (TDF) Organ that secretes testosterone and Mullerian inhibiting factor (MIF) Hormone that promotes development of external genitalia along male line Protein that transforms Wolffian ducts into male reproductive tract organs Organ that develops in the absence of TDF SRY gene sex-determining region Y protein initiating male sex determination Testosterone
b. The following diagram shows a family tree of individuals with haemophilia. B i. Based on an X-linked recessive pattern of inheritance, work out the likely genotypes of the individuals indicated by the letters. Individual A Individual B Individual C GENOTYPE ii. If individual C has children with a normal male, what are the chances that they will have haemophilia? Explain your answer fully. iii. If individual C has children with a normal male, what are the chances that their daughters will be carriers of the condition? Explain your answer fully.

1. Hemophilia is due to a sex-linked gene. It is recessive and found on the X chromosome. A woman who is a carrier for hemophilia marries a normal man. What will be the possible phenotypes of their children? Use a punnet square. 2. A phenotypically normal man, who has a hemophiliac brother, marries a normal woman, who is not a carrier. What is the probability that any of their children will be hemophiliac? Use a punnet square. 3. Color-blindness is an X-linked, recessive trait. If a normal-sighted woman, whose father was color-blind, marries a colorblind man, what is the probability that they will have a son who is color-blind? Use a punnet square. 4. A man and woman, both of normal vision, have: 1) a color-blind son (#1) who has a daughter of normal vision 2) a daughter (#1) of normal vision who has one color-blind son and one normal vision son 3) another daughter (#2) of normal vision who has five sons, all with normal vision What are the probable genotypes of the…
3. D. A. B. C. 10. Familial hypercholesterolemia is the most common genetic cause of heart disease. It is caused by a dominant factor (C). The recessive factor (c) produces a protein that processes cholesterol normally and leads to a normal risk for heart disease. Answer the following questions about the inheritance of this disease. What is the phenotype of a woman whose genotype is Cc? What is the genotype of a man who has hypercholesterolemia but whose mother did not have the disease? If a man who is heterozygous for the disease marries a woman who is heterozygous for the disease, what is the chance that any child of theirs will inherit the disease? If a man who is homozygous dominant marries a woman who is homozygous recessive, what would you predict for the the genotypes and phenotypes of their children? If the first 2 children from the marriage described in D above have the disease, what is the chance that a third child would be normal? Explain your answer. 41
